Can an object have a kinetic energy but no momentum?

FALSE – If an object does NOT have momentum, then it definitely does NOT have kinetic energy. However, it could have some potential energy and thus have mechanical energy.

Does higher kinetic energy mean higher momentum?

Does Momentum Increase with an Increase in Kinetic Energy? Ans. Since there is a relation between KE and momentum, KE increases with a rise in momentum.

Is kinetic energy related to momentum?

Some people think momentum and kinetic energy are the same. They are both related to an object’s velocity (or speed) and mass, but momentum is a vector quantity that describes the amount of mass in motion. Kinetic energy is a measure of an object’s energy from motion, and is a scalar.

Can two objects have the same momentum but different kinetic energy?

No. Momentum is simply mass times velocity. But kinetic energy is one-half the mass times the square of the velocity, so it’s much more dependent on the velocity than on the mass.

Can a single object have momentum?

Since its mass and velocity don’t change, its momentum won’t change either. This is true whatever the object happens to be – momentum must be conserved in any single-object system, as long as no net force acts on the system.

Can a single object have kinetic energy but no momentum can a system of two or more objects have total kinetic energy that is not zero but a total momentum that is zero?

Two objects of equal mass moving with equal speeds in opposite directions have a total momentum of zero, but their total kinetic energy is definitely nonzero. Basically, the kinetic energy of a system can never be zero as long as there is any kind of motion going on in the system.

Can you have negative momentum?

Momentum is a vector quantity, given by the product of an object’s mass and velocity. If the velocity of the object is negative, i.e. the object is traveling in what has been chosen as the negative direction, the momentum will also be negative.

When the momentum of an object increases with respect to time what is true of the net force acting on it?

When the momentum of an object increases with respect to time, what is true of the net force acting on it? It is zero, because the net force is equal to the rate of change of the momentum. It is zero, because the net force is equal to the product of the momentum and the time interval.
