What is the formula for calculating Kinetic Energy (KE)?

Back

KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

Calculate the Kinetic Energy of a 4 kg object moving at 3 m/s.

Back

18 J

Front

What is the formula for calculating Potential Energy (PE)?

Back

PE = m * g * h, where m is mass, g is acceleration due to gravity (9.81 m/s²), and h is height.

Front

Calculate the Potential Energy of a 6 kg child standing 5 meters above the ground.

Back

300 J

Front

What happens to the total energy in a closed system?

Back

The total energy remains the same (Law of Conservation of Energy).

Front

Define energy in a scientific context.

Back

Energy is the ability to do work.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy increases with the square of the velocity.

Front

What is gravitational potential energy dependent on?

Back

Gravitational potential energy depends on mass, height, and the acceleration due to gravity.

Front

How does energy transform in a roller coaster?

Back

Energy transforms between potential and kinetic energy as the coaster moves.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).
