The two main factors that affect kinetic energy are mass and speed. Why? Because the motion of an object depends on how fast it’s traveling, but also how much mass it has, though velocity is the more important factor.

v = velocity. Kinetic Energy Formula Questions.

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.

It turns out that an object’s kinetic energy increases as the square of its speed. A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph. Thus a modest increase in speed can cause a large increase in kinetic energy.

Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value.

=2J. Was this answer helpful?

Answer: as we know K.E=1/2mv^2 from this eqn we get K.E is directly proportional to square of velocity of body so, if we triple the velocity of body the K.E will become nine times of the initial K.E.I hope you got it. Answer: The Kinetic Energy is increased by a factor of 9 if the velocity is tripled.

What will be its kinetic energy when its velocity is increased three times? ∴ kinetic energy is directly proportional to square of velocity.

The kinetic energy of an object of mass, m moving with a velocity of 5 m s-1 is 25 J.

“Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.” Kinetic energy is a scalar quantity.

Answer. If velocity is doubled, Kinetic Energy increases by 4 times. Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.

Answer. KINETIC ENERGY WILL INCREASE WHEN MASS IS HALVED..
