Physics exam review flashcardziz

Front

What is Newton's Third Law of Motion?

Back

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

Front

Who developed the three laws of motion?

Back

Sir Isaac Newton.

Front

What does Newton's First Law of Motion state?

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 inertia?

Back

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

Front

What happens when two objects collide according to Newton's Third Law?

Back

They hit each other with the same force in opposite directions.

Front

What is the formula for Newton's Second Law of Motion?

Back

F = ma (Force equals mass times acceleration).

Front

What is an example of Newton's First Law in everyday life?

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What is the concept of force?

Back

A force is a push or pull that can cause an object to accelerate.

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.

Front

What is the Law of Universal Gravitation?

Back

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
