Momentum (True/False)

A ballistic pendulum is a device used to measure the velocity of slow particles.

False

A large force always produces a larger impulse on a body than a smaller force does.

False

An elastic collision is a collision in which momentum is conserved but kinetic energy is not.

False

If two particles have equal kinetic energies, they have equal momenta.

False

In a perfectly inelastic collision between two objects, both objects have equal kinetic energies after the collision.

False

In an inelastic collision momentum and kinetic energy are conserved.

False

Momentum is conserved regardless of whether or not friction is present.

False

Most collisions are elastic.

False

A ballistic pendulum is a device which allows us to calculate the velocity of a fast moving projectile.

True

A large force acting on an object will cause a large change in momentum.

True

FΔt = Δ p is the impulse momentum theory.

True

If two objects collide and one is initially at rest, it is impossible for both of them to be at rest after the collision.

True

Impulse is equal to the change in momentum.

True

In an elastic collision Kinetic Energy is conserved.

True

The equation for a perfectly inelastic collision is mv + mv = (m + m) vf.

True

The total momentum of an isolated system of objects is conserved regardless of the nature of the forces between the objects.

True

The units for Impulse are N . s

True

The units for force are Newtons, N.
