Newton's Laws & Forces

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 difference between mass and weight?

Back

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

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is fluid friction?

Back

Fluid friction is the resistance encountered by an object moving through a fluid (liquid or gas).

Front

What is rolling friction?

Back

Rolling friction is the force that opposes the motion of a rolling object.

Front

What factors affect the acceleration of an object?

Back

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

Front

What is inertia?

Back

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