Force & Net Force

Front

What is force?

Back

A force is a push or pull that can cause an object to move, change its speed, or change its direction.

Front

What is net force?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What happens to kinetic energy as a roller coaster car descends?

Back

As the car descends, its potential energy converts to kinetic energy, increasing its speed.

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 an unbalanced force?

Back

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

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 the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change speed.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; without force, an object will remain at rest or in uniform motion.

Front

What is an example of a balanced force?

Back

A book resting on a table is an example of balanced forces; the force of gravity is balanced by the normal force of the table.
