Newtons Laws Of Motion

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 a net external force.

Front

What does it mean for forces to be balanced?

Back

Balanced forces mean that the total net force acting on an object is zero, resulting in no change in motion.

Front

What is the definition of force?

Back

A force is a push or pull exerted on an object.

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 the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when a person pushes a stationary car, causing it to move.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What happens to an object in motion if no net external force acts on it?

Back

It continues to move at a constant velocity.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect the acceleration of an object?

Back

Greater mass results in less acceleration for the same amount of force applied.
