Impulse & Momentum

Front

The SI unit for momentum is: N^.kg, N^.m/s, m/s^.N, kg^.m/s

Back

kg^.m/s

Front

A large, slow-moving object has greater momentum than a smaller, slower object. Options: Always, Sometimes, Never

Back

Sometimes

Front

Linear momentum is defined as the product of a system’s ______________ multiplied by its _____________:

Back

mass, velocity

Front

What is Newton's 2nd Law of Motion?

Back

F = ma. An object acted on by an unbalanced force will accelerate in the direction of that force, in direct proportion to the strength of the force, and in inverse proportion to the mass of the object.

Front

Is momentum a quantity that can be conserved?

Back

Yes

For an object that hits a wall and bounces back, the Δp is: positive, negative, neutral

Back

negative
