Energy Types and Calculations

Front

At which point is potential energy greatest?

Back

Potential energy is greatest at the highest point in a system, where the object has maximum height and mass.

Front

Energy due to motion is ____________ energy.

Back

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

Front

The atom bomb has this type of ENERGY.

Back

Nuclear energy is the energy released during nuclear reactions, such as fission or fusion.

Front

The faster an object moves, the ________ kinetic energy it has.

Back

The faster an object moves, the more kinetic energy it has, as kinetic energy is proportional to the square of the velocity.

Front

Potential energy depends on __________.

Back

Potential energy depends on mass and height, as it is calculated using the formula PE = mgh (mass x gravity x height).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv² (1/2 x mass x velocity squared).

Front

What is the formula for calculating potential energy?

Back

The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is stored in food?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, such as food.

Front

What is mechanical energy?

Back

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

Front

What happens to kinetic energy when speed is doubled?

Back

If the speed of an object is doubled, its kinetic energy increases by a factor of four, since KE = 1/2 mv².
