Kinetic and Potential Energy-Ms J

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 associated with gravitational potential energy, calculated using PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What unit is Kinetic Energy measured in?

Back

Kinetic Energy is measured in Joules (J).

Front

What two factors affect an object's Potential Energy?

Back

The two factors that affect an object's Potential Energy are mass and height.

Front

How does height affect Potential Energy?

Back

As the height of an object increases, its Potential Energy increases, assuming mass remains constant.

Front

What is the formula for calculating Potential Energy?

Back

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

Front

If a 20 kg box is lifted 6 m above the ground, how much Potential Energy does it have?

Back

The Potential Energy is 1200 J (calculated using PE = mgh: 20 kg * 9.8 m/s² * 6 m).

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to mass; if mass increases while velocity remains constant, Kinetic Energy increases.

Front

How do you calculate Kinetic Energy?

Back

Kinetic Energy is calculated using the formula KE = 1/2 mv².

Front

If a 4 kg object is moving at a velocity of 3 m/s, what is its Kinetic Energy?

Back

The Kinetic Energy is 18 J (calculated using KE = 1/2 mv²: 1/2 * 4 kg * (3 m/s)²).
