Forces (net force, Balanced/unbalanced forces)

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is the net force of an object that is not moving?

Back

0 N (zero newtons) because the forces acting on it are balanced.

Front

What happens when forces are unbalanced?

Back

The object will move in the direction of the greater force.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward the Earth.

Front

What are balanced forces?

Back

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

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

If a net force of 400 N is acting downward, what does this indicate?

Back

It indicates that there is a greater force acting downward than upward, causing the object to accelerate downward.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car; if the push is strong enough, the car will move.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What is air resistance?

Back

Air resistance is a type of friction that acts against the motion of an object moving through the air.
