Newton's 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 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 strong nuclear force?

Back

It holds the protons and neutrons in the nucleus of the atom and overcomes the repulsion between the protons.

Front

What is terminal velocity?

Back

The constant velocity after which an object stops accelerating.

Front

What is friction?

Back

A force that resists motion in two objects that are moving against each other.

Front

How is speed defined?

Back

Speed is defined as distance divided by time; it is the rate at which an object moves.

Front

What is electromagnetic force?

Back

It determines the ways in which electrically charged particles interact with each other and with magnetic fields.

Front

What is inertia?

Back

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

Front

What factors affect the acceleration of an object?

Back

The net force acting on the object and the mass of the object.
