Unit 6: Newton's 3 Laws

Front

What is Newton's First Law of Motion?

Back

An object will remain at rest or in uniform motion unless acted upon by a net external force.

Front

What is the definition of inertia?

Back

Inertia is an object's resistance to changes in motion due to its mass.

Front

When two objects collide, how does the force they exert on each other compare?

Back

The forces exerted by both objects are equal in magnitude and opposite in direction.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

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

In the context of Newton's laws, what happens when a golf club hits a golf ball?

Back

The golf club exerts a force on the golf ball, causing it to accelerate.

Front

What is an example of action and reaction forces in nature?

Back

A bird's wings pushing down against the air (action) and the air pushing up against the wings (reaction).

Front

How does mass affect the acceleration of an object when a force is applied?

Back

A larger mass results in less acceleration for the same applied force, according to Newton's Second Law.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

Force (F) is calculated as mass (m) multiplied by acceleration (a), or F=ma.
