Newton's Laws of Motion Review for Flashcard

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it rubs against another surface, causing it to slow down or stop.

Front

What is a reaction in physics?

Back

A reaction is the outcome or result of an action, often described in terms of forces acting on objects.

Front

What does Newton's Third Law state?

Back

For every action, there is an equal and opposite reaction.

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 unless acted upon by a net external force.

Front

What happens to a rider when a horse stops quickly?

Back

The rider will continue moving forward due to inertia.

Front

What is inertia?

Back

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

Front

What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

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 an example of friction in everyday life?

Back

When you rub your hands together, the heat generated is due to friction.

Front

How does friction affect motion?

Back

Friction slows down moving objects and can eventually bring them to a stop.
