Week 8 - Newton's Laws

Front

What is the formula for force?

Back

F = M * A, where F is force, M is mass, and A is acceleration.

Front

What two factors does acceleration depend on?

Back

Acceleration depends on force and mass.

Front

According to Newton’s first law of motion, what happens to a moving object that is not acted on by an unbalanced force?

Back

It will remain in motion.

Front

What will happen to the girl on the sled if no outside force acts on her?

Back

She will remain in motion unless stopped by an outside force.

Front

Which of Newton's laws explains why motorists should buckle up?

Back

Newton's First Law of Motion explains that an object in motion will stay in motion unless acted upon by an outside force.

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 at a constant velocity unless acted upon by a net external force.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

According to Newton's Second Law, acceleration is inversely proportional to mass when force is constant.

Front

What is the formula for calculating acceleration?

Back

A = F / M, where A is acceleration, F is force, and M is mass.

Front

What does Newton's Third Law of Motion state?

Back

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

Front

How does friction affect motion according to Newton's laws?

Back

Friction is an unbalanced force that opposes motion, affecting the acceleration of an object.
