Newton's Laws, Friction & Momentum Flashcard

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

What is the unit of force?

Back

The unit of force is Newtons (N).

Front

What does momentum depend on?

Back

Momentum depends on the mass and velocity of an object, calculated using the formula p=mv.

Front

What is the unit for momentum?

Back

The unit for momentum is kg·m/s.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What are the types of friction?

Back

The types of friction include static friction, kinetic friction, and rolling friction.

Front

How do you calculate momentum?

Back

Momentum is calculated using the formula p=mv, where p is momentum, m is mass, and v is velocity.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by Newton's 2nd Law: F=ma, meaning force equals mass times acceleration.

Front

What happens to momentum in a closed system?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event (conservation of momentum).
