Newtons Laws Of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's 2nd 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)

What is a contact force?

Back

A force that requires contact between two objects, such as friction or tension.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between surfaces.

Front

What is inertia?

Back

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

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, affecting their motion.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The object will not move at all.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
