Newton's Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced 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 a force?

Back

A push or pull on an object.

Front

What is inertia?

Back

The resistance of an object to any change in its motion.

Front

What is an unbalanced force?

Back

A force that causes an object to accelerate, as the forces acting on it are not equal.

Front

What is a balanced force?

Back

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

Front

What is the relationship between mass and acceleration?

Back

As mass increases, acceleration decreases for a given force (according to Newton's 2nd Law).

Front

What happens to a stationary object when an unbalanced force is applied?

Back

It will start to move in the direction of the applied force.

Front

What is the effect of gravity on objects?

Back

Gravity pulls objects toward the center of the Earth, giving them weight.
