Newton's 2nd & Momentum Review

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

How do you calculate force using mass and acceleration?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What is the principle of conservation of momentum?

Back

The principle states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

If an object has a mass of 10 kg and an acceleration of 2 m/s², what is the force?

Back

20 N.

Front

What happens to momentum during a collision?

Back

Momentum is conserved; the total momentum before the collision equals the total momentum after the collision.

Front

What two quantities are needed to calculate momentum?

Back

Mass and velocity.

Front

If a 50 kg ball rolls at 5 m/s, what is its momentum?

Back

250 kg*m/s.

Front

What is the relationship between mass, velocity, and momentum?

Back

Momentum increases with either an increase in mass or an increase in velocity.
