Forces and Energy Concepts

Who discovered the force that keeps us on the ground?

• Leonardo da Vinci

• Oliver Cromwell

• Isaac Newton

• Francis Bacon

What makes speed different from velocity?

• Velocity and speed are the same thing.

• Speed isn't a scientific measurement.

• Speed is how fast something moves, and velocity is how slowly it moves.

• Velocity has direction while speed does not.

What is the formula for gravitational potential energy?

• PE = MGH

• PE = m^2 GH

• PE = 1/2 MGH

• PE = GH^2

What type of energy is related to motion?

• Gravitational potential energy

• Kinetic energy

• Thermal energy

• Chemical energy

How does the velocity of an object affect its kinetic energy?

• Velocity and kinetic energy are unrelated.

• Higher velocity means higher kinetic energy.

• Velocity does not affect kinetic energy.

• Higher velocity means lower kinetic energy.
