Net Forces Review

Front

What is the net force acting on an object?

Back

The net force is the overall force acting on an object after all the individual forces are combined.

Front

What is the unit of force?

Back

The unit of force is called a Newton (N).

Front

If you push on an object with a force of 20 N and it does not move, what is the force exerted back on you?

Back

The object exerts a force of 20 N back on you.

Front

What type of force is acting on an object when the resulting force is greater than zero?

Back

An unbalanced force is acting on the object.

Front

What is a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens to an object when unbalanced forces act on it?

Back

The object will accelerate in the direction of the net force.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is an example of an unbalanced force?

Back

A person pushing a car that is stuck in mud; the force of the push is greater than the friction.
