kinetic and potential energy

Front

What does the law of conservation of energy state?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

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

Front

How is kinetic energy calculated?

Back

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

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity.

Front

What is potential energy?

Back

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

Front

How is gravitational potential energy calculated?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the relationship between kinetic and potential energy in a pendulum?

Back

In a pendulum, kinetic energy is highest at the lowest point of the swing, while potential energy is highest at the highest points of the swing.

Front

What happens to kinetic energy during a collision?

Back

During a collision, kinetic energy can be transferred from one object to another, and some may be converted to other forms of energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of kinetic and potential energy in a system.

Front

How does speed affect kinetic energy?

Back

The kinetic energy of an object increases with the square of its speed; if speed doubles, kinetic energy increases by a factor of four.
