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 gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What two factors does kinetic energy depend on?

Back

Kinetic energy depends on velocity and mass.

Front

At which point in a roller coaster's path is potential energy the greatest?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What force attracts objects towards the Earth?

Back

Gravity is the force that attracts objects towards the surface of the Earth.

Front

What is kinetic energy?

Back

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

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and gravitational potential energy?

Back

Gravitational potential energy increases with an increase in mass and height.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
