AC Newtons Laws Take home Test

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

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. This is often summarized by the formula F = ma.

Front

What does the term 'force' mean in physics?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = F/m, where F is the net force and m is the mass.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is an example of Newton's First Law?

Back

A soccer ball remains at rest until a player kicks it.

Front

What is an example of Newton's Second Law?

Back

A heavier object requires more force to accelerate than a lighter object when both are pushed with the same force.

Front

What is an example of Newton's Third Law?

Back

When a swimmer pushes the water backwards, the water pushes the swimmer forward.

Front

What are the appropriate units to describe force?

Back

The appropriate units to describe force are Newtons (N).
