How does the kinetic energy of a moving body depends on its speed?
(i) Kinetic energy of a moving body is directly proportional to the square of the speed of the moving body. (ii) Kinetic energy of a moving body is directly proportional to the mass of the moving body.
How will the kinetic energy of an object change if its speed is halved?
Answer: Ek is directly proportional to the square of speed of a body. So, if speed is halved, kinetic energy becomes one fourth of the original.
When the speed of a car is halved the kinetic energy is what?
Given K1 = mv²/2. Hence, the initial kinetic energy is quartered.
What is the effect on the kinetic energy of a moving car if velocity is halved?
Kinetic Energy = (1/2) mv2. If the velocity of a body is halved, its kinetic energy becomes one fourth as kinetic energy is directly proportional to velocity squared. Asked by Byjus on June 25, 2016 in Physics.
What happens to kinetic energy when mass is halved?
Answer. KINETIC ENERGY WILL INCREASE WHEN MASS IS HALVED..
What is the effect on the kinetic energy of a moving car?
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.
What is the kinetic energy of a body of mass 1 kg?

What is the kinetic energy of a jogger?
Answer: Kinetic energy=1/2mv^2. 1/2×65×2.5^2.
What is the kinetic energy of a car that is traveling with a speed of 40 m/s and has a mass of 1120 kg?
252 Joules
What is the kinetic energy of a ball with a mass of 0.5 kg?
The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J. The unit Joule (J) is the same as kgm^2/s^2 and is the SI unit for kinetic energy.
What is the kinetic energy of a 2kg rabbit hopping at a speed of 1.25m s?
What is the kinetic energy of a 2kg rabbit hopping at a speed of 1.25 m/s? 1.5625 J 12. The mass of a golf club is 0.6 kilograms.
What letter does the ball have the greatest 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.
