What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect kinetic energy?

Back

As mass increases, kinetic energy increases if the speed remains constant. This is because kinetic energy is directly proportional to mass.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, most notably the force that pulls objects toward the center of the Earth.

Front

What is the boiling point of water?

Back

The boiling point of water at standard atmospheric pressure is 100°C.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed. If speed doubles, kinetic energy increases by a factor of four.

Front

What is the order of distances in the universe?

Back

Distances in the universe can be compared and ordered based on their measurements, such as light-years or kilometers.

Front

Which planet is known as the Red Planet?

Back

Mars is known as the Red Planet due to its reddish appearance, which is caused by iron oxide (rust) on its surface.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the difference between mass and weight?

Back

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

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.
