7 Momentum Review

Front

What are the units for FORCE?

Back

Newtons

Front

If 2 objects collide and stick together, what will happen to their velocities?

Back

Velocities will decrease.

Front

Momentum is conserved in this type of collision.

Back

Momentum is conserved in both elastic and inelastic collisions.

Front

What is the relationship between force and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What happens to kinetic energy in an inelastic collision?

Back

Kinetic energy is not conserved; some energy is transformed into other forms.

Front

What is an elastic collision?

Back

A collision where both momentum and kinetic energy are conserved.

Front

What is an inelastic collision?

Back

A collision where momentum is conserved, but kinetic energy is not.

Front

What is the formula for momentum?

Back

Momentum (p) is the product of mass (m) and velocity (v), p = mv.

Front

How does mass affect momentum?

Back

Greater mass results in greater momentum if velocity is constant.
