Q. Which best describes the conservation of energy as a pendulum swings in the path shown below?
Answer Expert Verified The conservation of energy as a pendulum swings in the path would be that the potential energy at point a is greater than the kinetic energy at point b. Hope this answers the question.
Q. How does a pendulum show conservation of energy?
When a pendulum swings, potential energy is transformed into kinetic energy, and then back again to potential energy as the speed and elevation of the pendulum vary during the motion.

Q. Is energy conserved when a pendulum swings?
In a simple pendulum with no friction, mechanical energy is conserved. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy. …
Q. What energy changes occur as a pendulum swings?
As a pendulum swings, its potential energy converts to kinetic and back to potential. Recall the concept of conservation of energy—that energy may change its form, but have no net change to the amount of energy.
Q. Why does a pendulum eventually stop swinging?
When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.
Q. When a pendulum swings at which point is potential energy highest?
The pendulum has zero speed and zero kinetic energy at the top of its swing and at the bottom. Its gravitational energy is largest at the top of its swing and smallest at the bottom.
Q. Which point has the highest potential energy?
The potential energy is highest at point A and the kinetic energy is lowest. Kinetic energy is highest at point B and potential energy is lowest. The gravitational potential energy in the heavy weight is turned into kinetic energy.
Q. When a pendulum swings at which point is potential and kinetic energy equal?
Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its swing when the weight is moving fastest.
Q. At which position in the pendulum swing is kinetic energy greatest?
Kinetic energy is highest when the velocity is the highest. This occurs at the bottom of the pendulum.
Q. Which is the best example that something has kinetic energy?
What are some examples of kinetic energy? when you are walking or running your body is exhibiting kinetic energy. A bicycle or skateboard in motion possesses kinetic energy. Running water has kinetic energy and it is used to run water mills.
Q. What is the potential energy of a pendulum?
The potential energy of the pendulum is 0 when the pendulum is at its equilibrium position. Therefore, at this point, the mechanical energy E is equal to the kinetic energy KE (all the energy at the equilibrium position is kinetic).
Q. What are the two factors that affect kinetic energy?
1. Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object’s kinetic energy. 2.
Q. What are the factors that affect kinetic and potential energy?
Since the state of motion of an object can change with time, the kinetic energy of an object can also change with time. The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy.
Q. What affects kinetic energy the most?
In fact, kinetic energy is directly proportional to mass: if you double the mass, then you double the kinetic energy. Second, the faster something is moving, the greater the force it is capable of exerting and the greater energy it possesses.
Q. Which ball has the most kinetic energy?
As the ball falls from C to E, potential energy is converted to kinetic energy. The velocity of the ball increases as it falls, which means that the ball attains its greatest velocity, and thus its greatest kinetic energy, at E. 19.
Q. What are the similarities and differences of potential energy and kinetic energy?
Kinetic energy is energy possessed by a body by virtue of its movement. Potential energy is the energy possessed by a body by virtue of its position or state. While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment.
Q. Why does kinetic energy increase with the square of velocity?
Why does kinetic energy increase with the square of velocity? Therefore the work done (force times distance) is proportional to the square of initial velocity. Since energy is conserved, that work becomes kinetic energy, and therefore kinetic energy increases with the square of velocity.
Q. Does a car’s kinetic energy change more when the car speeds up from 10 to 15 m/s or from 15 to 20 m s?
The kinetic energy changes more if the car goes from 15 m/s to 20 m/s.
Q. Which has more kinetic energy a 40 kg cheetah running at 25 m/s or a 4000 kg elephant moving at 2 m/s how much more energy does it have?
Answer: 1. The elephant has more kinetic energy at this speed and mass. It has 4,500 J more KE.
Q. What is the relationship between energy and speed?
The relationship between kinetic energy and speed as a nonlinear (square) proportional relationship (KE ∝ v2) in which: 1. The kinetic energy quadruples as the speed of the object doubles. 2. The kinetic energy decreases by a factor of four as the speed of the object is cut in half.
Q. What adds more kinetic energy mass speed or length?
The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with equal mass and twice the speed will have quadruple the kinetic energy.
Q. What will happen to the kinetic energy of a body if its mass is doubled?
The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
Q. When a person is sledding down a hill where do they have the most kinetic energy?
At the bottom of the hill, you have the most kinetic energy because you are moving the fastest and all the potential energy has turned into kinetic. Sledding only works when there is snow on the ground, if you try to go sledding on a grassy hill it won’t be as fun because snow helps to eliminate friction.
Q. What happens when the mass is doubled?
As mass is doubled, acceleration becomes half. …
Q. What happens to the gravitational force when the mass is doubled?
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Q. What happens to acceleration when mass is increased?
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.
