Newtons Laws of Motion

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 does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is gravity?

Back

The attractive force that exists between all objects that have mass.

Front

What happens to an object when the forces acting on it are unbalanced?

Back

The object will accelerate in the direction of the net force.

Front

What is inertia?

Back

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

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is the relationship between acceleration and mass according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.
