Newtons laws

Front

What is Newton's 1st law of motion?

Back

An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

Front

What is Newton's 2nd law of motion?

Back

The net force acting upon an object is equal to the mass of the object multiplied by its acceleration (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 inertia?

Back

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

Front

What does it mean when we say an object is at rest?

Back

An object is at rest when it is not moving and remains in the same position.

Front

What is the definition of force?

Back

A force is a push or pull acting upon an object.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant speed in a straight line.

Front

What is an example of action and reaction forces?

Back

When a swimmer pushes the water backward, the water pushes the swimmer forward.

Front

What is the relationship between mass and acceleration in Newton's 2nd law?

Back

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