Newtons Laws

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 inertia?

Back

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

Front

What is force?

Back

A push or pull exerted on an object.

Front

What is net force?

Back

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

Front

What is weight?

Back

The force of gravity acting on an object, calculated as mass times the acceleration due to gravity (W=mg).

Front

What is the relationship between mass and weight?

Back

Weight is the force due to gravity acting on a mass; weight varies with the strength of the gravitational field.

Front

What does it mean for forces to be balanced?

Back

When two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

When the forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.
