Front

When the speed of an object is doubled, what happens to its momentum?

Back

Its momentum doubles.

Front

Momentum is a ____________________ quantity.

Back

Momentum is a vector quantity.

Front

What is the formula to calculate speed?

Back

S = d/t

Front

This equation goes with which law? F = ma

Back

Newton's second law of motion.

Front

Which runner stopped for a rest?

Back

Charlie.

Front

What is the definition of momentum?

Back

Momentum is the product of an object's mass and its velocity.

Front

What is the unit of momentum?

Back

The unit of momentum is kg·m/s.

Front

What does Newton's first law of motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the formula for Newton's second law of motion?

Back

F = ma (Force equals mass times acceleration).

Front

What is the difference between scalar and vector quantities?

Back

Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
