Energy and Momentum

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It is often associated with the height of an object above the ground.

Front

What determines the amount of Potential Energy a skier has at the top of a ramp?

Back

The amount of Potential Energy a skier has is equal to the work it took to get the skier to the top of the ramp.

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

Which has a greater impact on Kinetic Energy: mass or velocity?

Back

Velocity has a greater impact on Kinetic Energy.

Front

How does an increase in mass affect Kinetic Energy?

Back

As mass increases, Kinetic Energy increases.

Front

What is the SI unit of Kinetic Energy?

Back

The SI unit of Kinetic Energy is Joules.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

Define mass in the context of physics.

Back

Mass is a measure of how much matter an object has, typically measured in kilograms.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force acting on an object is directly proportional to its mass.
