Chapter 2 Review

Front

What is circular motion?

Back

Circular motion is the motion of an object that moves along a circular path. It can be uniform (constant speed) or non-uniform (changing speed).

Front

What is an example of a situation that is NOT circular motion?

Back

A car accelerating onto a highway is NOT an example of circular motion.

Front

What does Newton's Second Law state?

Back

Newton's Second Law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What is the significance of Newton's First Law?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What does Newton's Third Law state?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is static friction?

Back

Static friction is the force that must be overcome to start an object moving from rest.

Front

How does gravity affect falling objects?

Back

Gravity causes objects to accelerate downwards towards the Earth, resulting in a falling motion.

Front

What is the relationship between force, mass, and acceleration?

Back

The relationship is defined by Newton's Second Law, which states that force equals mass times acceleration (F = ma).

Front

Can you give an example of Newton's Third Law in action?

Back

An example of Newton's Third Law is when you push against water while swimming; the water pushes you forward.

Front

What is the difference between static friction and kinetic friction?

Back

Static friction acts on an object at rest, preventing it from moving, while kinetic friction acts on an object in motion, opposing its movement.
