Introduction to Energy

Learning Target: I can identify and investigate Newton's laws of motion

Warm-up 1/23/2020

• What is the name of the force that allows objects to float? (Hint: Look it up)
• Which of Newton's laws would you need to use to determine the force required to accelerate a rocket with a specific mass?
• If it were a windy day what force factor(s) would you need to consider if you were trying to jump a motorcycle across the grand canyon?

Word Wall

Kinetic Energy - The energy of motion

Potential Energy - Stored energy. The energy held by an object because of its position relative to other objects.

Mass - The quantity of matter within a body

Speed - The distance traveled per unit of time

Velocity - speed plus direction

Work - using a force to move an object

Motion - a change in position

Energy - the ability to do work.

Law of conservation of energy - states that energy cannot be created or destroyed; it can only be changed from one form of energy to another.

Acceleration - rate of change of speed or a change in direction

Force - a push or a pull on an object

Friction - The resistance that an object or surface encounters when moving over another.

Inertia - the tendency of an object to continue at rest or to remain in motion based on its mass
