LESSON 2 Let’s get Physical

Collision When two objects come together with great force Another example is when you hit your little brother or sister :) but don’t promote violence, only peace man.

Inertia An object’s resistance to movement or change in direction Inertia keeps an object going straight, like in the gif above!

Newton’s First Law of Motion An object at rest will stay at rest and an object in motion will stay in motion unless a force changes state of motion Friction and wind speed can slow down objects, often being the case.

Newton’s Third Law of Motion For every action there is an equal and opposite reaction Then the boat moves forward, there is a force going the opposite direction in the water. May the Force be with you

Simple Machines One of 6 basic machines with few or moving parts. Inclues inclined planes, levers, wedges, screws, pulleys, and wheel and axle.

Fulcrum The point where a lever rocks back and forth The fulcrum is triangular guy with a smiley face on him

Screw An inclined plane around a post, used to hold things together Discuss the difference between screws, nuts, and bolts

Sphere Perfectly round, 3D shape that looks like a ball Like a 3D circle, discuss other spherical objects (balls, etc.)

Complex and Compound Machines Includes 2 or more machines. Discuss which simple machines are a part of each example picture
