Front

Using the p=mv formula, calculate the MOMENTUM of a 5 kg bird flying south at 20 m/s.

Back

100 kg⋅m/s

Front

What is the formula for momentum?

Back

p=mv

Front

What is Newton's 1st Law of Motion?

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 Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the unit of momentum?

Back

kg⋅m/s

Front

What does friction do to the motion of an object?

Back

Friction opposes the motion of an object.
