Forces Summative Review

Front

What is Equilibrium?

Back

Equilibrium is when all the forces that act upon an object are balanced.

Front

If an object has a mass of 2 kg and experiences a net force of 11 N, what is its acceleration?

Back

Acceleration = Force / Mass = 11 N / 2 kg = 5.5 m/s².

Front

What is a force pair?

Back

A force pair consists of two forces that are equal in size, opposite in direction, and act on two different objects.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What does it mean for a force to be unbalanced?

Back

An unbalanced force results in a change in the motion of an object.

Front

How do you calculate net force when two forces act in the same direction?

Back

Add the magnitudes of the forces together.

Front

How do you calculate net force when two forces act in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What is the formula for calculating acceleration?

Back

Acceleration = Net Force / Mass.
