What is energy?

Back

Energy is the ability to do work or cause change. It can exist in various forms, such as kinetic, potential, thermal, and more.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, depending on their masses and the distance between them.

Front

What factors affect gravitational attraction?

Back

Gravitational attraction is affected by the masses of the objects and the distance between them. Greater mass and closer distance increase attraction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state. For example, a raised object has gravitational potential energy.

Front

How does energy transform when a toy is wound up and released?

Back

When a toy is wound up, it stores potential energy. When released, this energy transforms into kinetic energy as the toy moves.

Front

What is the formula for calculating speed?

Back

Speed is calculated using the formula: Speed = Distance / Time.

Front

If a cyclist travels 24 km in 1.2 hours, what is their speed?

Back

The speed is 20 km/h, calculated as 24 km / 1.2 h.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
