Kinetic energy of a moving object varies directly with the square of velocity If a car moving at 60mph has kinetic energy 180 units how many units of kinetic energy does the same car have at 20mph?

The "units" are called joules (J), not to be impolite. The answer would be about 19.9809 J.

Kinetic energy is directly proportional to?
Kinetic energy should be called vector energy and is directly proportional to velocity, Ekinetic= mcV.
Is kinetic energy is the energy an object has to due to its motion?
kinetic energy-energy in motion object that change from being at rest
Does a strawberry have kinetic energy?
If the strawberry is moving, it has kinetic energy. Anything with a mass and velocity has kinetic energy.
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
What is considered when measuring kinetic energy?
Kinetic energy cannot be measured directly, but the kinetic energy is just 1/2 times the mass times the velocity squared, and velocity can be measured directly.

When you have kinetic energy you must have?
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
Does a strawberry have kinetic energy?
If the strawberry is moving, it has kinetic energy. Anything with a mass and velocity has kinetic energy.
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
What happends to kinetic energy when the velocity increases?
Kinetic energy is proportional to the square of the magnitude of velocity.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
Kinetic energy is directly related to?
it is directly related to the weight or mass of an object
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
What happens to an objects kinetic energy as its mass increases?
kinetic energy, K.E = 1/2 mv^2 that is, it is directly proportional to mass, assuming velocity to be constant and is directly proportional to square of velocity assuming mass to be constant.
How do weight and kinetic energy relate?
Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.
