Transcript of Force and Motion Unit Plan

Who is....
Sir Isaac Newton?
Sir Isaac Newton was a scientist and mathematician who lived in the 1600s. Newton came up with some very important explanations about force and motion that we still use today. Newton also developed three laws of motion that explain how and why objects stop and go.
Newton's First Law Of Motion
Objects in motion stay in motion and objects at rest stay at rest unless acted upon by an outside force
Newton's Second Law of Motion
May the Force Be With You

MAY THE FORCE BE WITH YOU
Newton's First Law: This shows that an object at rest remains at rest, and that an object in motion stays in motion unless a
force
is applied. The first bird is the object in
motion
, and it remains in motion until it hits another object, so a force is applied. The second bird remains at rest when it is on the ground.
Newton's First Law
Objects in motion stay in motion and objects at rest stay at rest unless acted upon by an outside force.
Friction
The force that acts on an object to slow it down.
Force
A push or pull on an object.
Acceleration
An increase in speed or velocity.
Energy
The ability to do work.
Equilibrium
A state of balance where opposing forces on an object simply cancel each other out, and the object remains stable and unchanged.
Gravity
A force that pulls anything on the Earth’s surface toward the center of the Earth.
Momentum
The strength or force that something has when it is moving
Motion
Changing in places or positions.
Speed
Measurement of distance over time.
Newton's Second Law
Acceleration of an object depends on the force and mass.
Newton's Third Law
For every action there is an equal and opposite reaction.
Velocity
How fast and in what direction an object is traveling.
This shows how an object accelerates or changes direction when a force is applied, and how acceleration due to a force is always in the direction of the force.
Newton's Third Law of Motion
This shows how for every action, there is an equal and opposite reaction. The slingshot was pulled back, so the opposite reaction was that the bird shot forwards.
Inertia
When an object remains still or moves in a constant direction at a constant speed.
