Kinetic and Potential Energy Flashcard

Front

What happens to the potential and kinetic energy of a pendulum as it swings from its highest to lowest position?

Back

The potential energy decreases while the kinetic energy increases.

How does the mass of an object affect its kinetic energy?

Back

The kinetic energy of an object is directly proportional to its mass; a heavier object (like a truck) will have more kinetic energy than a lighter object (like a car) if both are moving at the same speed.

What type of energy is stored when a rubber band is stretched?

Back

Elastic potential energy.

Front

What is the formula for calculating kinetic energy?

Back

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

What is potential energy and how is it calculated?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

What is the relationship between kinetic energy and speed?

Back

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

How does energy conservation apply to a swinging pendulum?

Back

The total mechanical energy of a pendulum remains constant if we ignore air resistance and friction; energy transforms between kinetic and potential forms.
