Kinetic and Potential Energy

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 mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is height.

Front

What happens to Kinetic Energy if the speed of an object doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object. If the mass increases, the Kinetic Energy increases, assuming the velocity remains constant.

Front

What is the relationship between height and Potential Energy?

Back

Potential Energy is directly proportional to the height of an object. As the height increases, the Potential Energy increases, assuming mass and gravity remain constant.

Front

What is the formula for calculating gravitational potential energy?

Back

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

Front

At which point is Kinetic Energy greatest in a roller coaster?

Back

Kinetic Energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

At which point is Potential Energy greatest in a roller coaster?

Back

Potential Energy is greatest at the highest point of the roller coaster, where the height is maximum.
