Newtons Laws Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second 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 Third Law of Motion?

Back

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

Front

What is the unit of force?

Back

Newton (N)

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is friction?

Back

The force that opposes motion between two surfaces in contact.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that do not cancel each other out, resulting in a change in motion.

Front

What is momentum?

Back

The product of an object's mass and its velocity (p = mv).

Front

What is gravity?

Back

The force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.
