Force and Motion Review

Front

What is the net force on an object?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, change direction, or change shape.

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 is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is a force?

Back

A force is any push or pull on an object.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

What is air resistance?

Back

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

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 happens when the net force is zero?

Back

When the net force is zero, the object remains at rest or continues to move at a constant velocity.

Front

What is the effect of an unbalanced force on a soccer ball?

Back

An unbalanced force will cause the soccer ball to accelerate in the direction of the net force.
