Chapter 3 Review

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = m x v).

Front

What is the unit of momentum?

Back

The unit of momentum is kg x m/sec.

Front

What does the conservation of momentum state?

Back

The total momentum of a closed system remains constant unless acted upon by external forces.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with greater mass if velocity is constant.

Front

What is an example of a force acting in pairs?

Back

When you push against a wall, the wall pushes back with equal force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

Greater mass means greater inertia, making it harder to change the object's motion.

Front

What is the formula for calculating momentum?

Back

Momentum (p) = mass (m) x velocity (v).

Front

What happens to momentum in a collision?

Back

In a closed system, the total momentum before the collision equals the total momentum after the collision.
