Kinetic & Potential Energy Calculations

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where KE is Kinetic Energy, m is mass in kilograms, and v is velocity in meters per second.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is often associated with gravitational energy, calculated using PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the formula for calculating Potential Energy?

Back

PE = mgh, where PE is Potential Energy, m is mass in kilograms, g is acceleration due to gravity (approximately 9.81 m/s²), and h is height in meters.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more Kinetic Energy it has. Kinetic Energy increases with the square of the speed.

Front

What factors affect Potential Energy?

Back

Potential Energy depends on the height and mass of the object. Higher mass and greater height result in more Potential Energy.

Front

If an object has a mass of 150 kg and is moving at 15 m/s, what is its Kinetic Energy?

Back

The Kinetic Energy is 16,875 J.

Front

If Ty lifts a 1250 kg weight to a height of 2 m, what is the Potential Energy?

Back

The Potential Energy is 24,500 J.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object. More mass means more Kinetic Energy if speed is constant.

Front

What is the relationship between height and Potential Energy?

Back

Potential Energy is directly proportional to the height of the object. Higher height means more Potential Energy if mass is constant.
