Lifting a ball into the air before dropping it gives it a type of energy called ‘potential energy’ – which means the ball has the potential to do some work. When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy.
Q. Where does the energy go when a ball bounces?
When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. When it reaches Earth, it collides head-on with an incredibly massive object that is, from your perspective, at rest. The ball slows down, deforms temporarily and shoots back up.

Q. At what position does the ball have the most potential energy?
The ball at the top of the swing is briefly motionless. It has the greatest potential energy, because it is highest above the surface. At every point in the swing, the system of the ball on the pendulum string has the same total amount of energy.
Q. At what point on a swing do you have the most kinetic energy?
The kinetic energy of the pendulum is greatest at the bottom of the swing and least at the tops of the swing. Kinetic energy increases as the pendulum swings downward and decreases as the pendulum swings upward.
Q. Why do pendulums eventually stop?
A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. 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. What are the relationships between kinetic energy and potential energy in a pendulum swing?
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 does the child on the swing have the most kinetic energy?
At what position does the girl on the swing have the most potential energy? The girl on the swings has the most kinetic energy at the bottom of her swing because she has the most speed at that point.
Q. Where is ke the highest?
Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
Q. What is the formula for GPE and do a calculation?
The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.
Q. What does GPE depend on?
Gravitational potential energy depends on an object’s weight and its height above the ground (GPE = weight x height). Elastic potential energy is due to an object’s shape.
Q. Is potential energy ever negative?
Yes,potential energy can be negative. Potential energy is a relative concept which depends on the frame of reference which has been chosen as zero potential. Yes,potential energy can be negative. Potential energy is a relative concept which depends on the frame of reference which has been chosen as zero potential.
Q. What is the meaning of negative potential?
: an electric potential lower than that of the earth or other conductor taken as an arbitrary zero of potential.
Q. What is kinetic energy at infinity?
The distance that is required to escape a body’s gravitation is known as the infinite distance. You can escape the earth’s gravitation after an infinite distance. Therefore, the kinetic energy at infinity is zero.
Q. Is total energy Zero Infinity?
At infinity, the gravitational potential energy of the satellite is zero. As the. Earthsatellite system is a bound system, the total energy of the satellite is negative. Thus, the total energy of an orbiting satellite at infinity is equal to the negative of its kinetic energy.
