Energy Transformations and Potential Energy

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as mechanical energy to electrical energy.

Front

What type of energy is produced when a hand generator is turned?

Back

Mechanical energy is transformed into electrical energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

Which ball has more potential energy if Ball A is higher than Ball B?

Back

Ball A has more potential energy because it is at a greater height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

At which position does an object have the greatest kinetic energy when rolling down a hill?

Back

The object has the greatest kinetic energy at the lowest point of the hill.

Front

What is thermal energy?

Back

Thermal energy is the energy of heat that transfers from hotter objects to colder objects.

Front

How does the speed of particles relate to thermal energy?

Back

The faster the particles in an object move, the more thermal energy is produced.

Front

What is the formula for calculating net force?

Back

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

Front

If two forces of 60N and 40N act in opposite directions, what is the net force?

Back

The net force is 20N in the direction of the larger force.
