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 at a constant velocity unless acted upon by a net external 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 net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

What is inertia?

Back

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

Front

What is mass?

Back

The amount of matter in an object, usually measured in kilograms.

Front

What is acceleration?

Back

The rate of change of velocity of an object, measured in meters per second squared (m/s²).
