KINETIC AND POTENTIAL ENERGY Exit Slip

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 Potential Energy?

Back

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

Front

How do you calculate Kinetic Energy?

Back

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

Front

How do you calculate Potential Energy?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height above the ground.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).

Front

If a cheetah has a mass of 47.0 kg and runs at 31.0 m/s, what is its Kinetic Energy?

Back

The Kinetic Energy is 22,583 Joules.

Front

If a polar bear has a mass of 500.0 kg and runs at 11.0 m/s, what is its Kinetic Energy?

Back

The Kinetic Energy is 30,250 Joules.

Front

What factors affect Kinetic Energy?

Back

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

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the mass of the object, the height above the ground, and the acceleration due to gravity.

What is the relationship between Kinetic and Potential Energy in a roller coaster?

Back

In a roller coaster, energy transforms between Kinetic and Potential Energy as the coaster moves up and down hills.
