Kinetic and Potential Energy CSA Review

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

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its velocity. Increasing either mass or velocity increases kinetic energy.

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.

Front

How does velocity relate to Kinetic Energy?

Back

Velocity is a key factor in determining Kinetic Energy; as velocity increases, Kinetic Energy increases exponentially since it is squared in the formula.

Front

What is the relationship between mass and Potential Energy?

Back

The greater the mass of an object, the greater its Potential Energy when at a certain height. More mass means more energy stored.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

Which object has more Potential Energy: a ball on the ground or a ball on a cliff?

Back

A ball on a cliff has more Potential Energy because it is at a greater height compared to a ball on the ground.

Front

What happens to Kinetic Energy when an object slows down?

Back

When an object slows down, its Kinetic Energy decreases because Kinetic Energy is directly related to the square of its velocity.

Front

How can work affect Kinetic Energy?

Back

When work is done on an object, it can increase its Kinetic Energy. For example, pushing a stationary object gives it Kinetic Energy.
