Conservation of Energy

Front

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

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

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

Back

PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to the total mechanical energy in a closed system?

Back

The total mechanical energy remains constant; it is conserved.

Front

Define Kinetic Energy.

Back

Kinetic Energy is the energy of an object due to its motion.

Front

Define Gravitational Potential Energy.

Back

Gravitational Potential Energy is the energy stored in an object as it is raised above the ground.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to mass; if mass increases, KE increases.

Front

What is the relationship between velocity and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the square of velocity; if velocity doubles, KE increases by a factor of four.

Front

What is Static Friction?

Back

Static Friction is the force that resists the initiation of sliding motion between two surfaces in contact.

Front

What happens to Potential Energy as an object falls?

Back

Potential Energy decreases as the object falls, converting to Kinetic Energy.

Front

What is the principle of conservation of energy?

Back

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