Force and Motion Review

Front

What is the standard unit force is measured in?

Back

Newtons

Front

Which would require the most force to move?

Back

a chair with a friend sitting in it

Front

What is the force between two objects that slows and stops motion?

Back

friction

Front

What is the tendency of an object that is at rest to stay at rest or if in motion to stay in motion?

Back

inertia

Front

If two men are pulling with the same amount of force, what will happen?

Back

They will not move at all.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma)

Front

What is the effect of friction on motion?

Back

Friction opposes motion and can slow down or stop moving objects.

Front

What is inertia and how does it relate to mass?

Back

Inertia is the resistance of an object to change its state of motion; it is directly related to the object's mass.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on moving objects.

Front

How does increasing mass affect the force required to move an object?

Back

Increasing mass increases the force required to accelerate the object, according to F = ma.
