One
The speed and direction of a moving objects
Velocity
The amount of “stuff” in an object
Mass
the change in position of an object
Motion
An object’s tendency to resist a change in motion
Inertia
The force that pulls objects toward each other
Gravity
The sum of all forces acting on an object
Net Force
Speed
A push or pull of an object
Force
The amount of force that gravity has on an object’s mass
Weight
The rate at which an object change speed and direction
Acceleration
The force that slows down objects when they rub against each other
Friction
The force exerted by a magnet on certain other materials.
Magnetism
What is Newton’s 3rd Law of Motion?
For every action there is a reaction.
To determine net force, you need to know…
The strength and direction of all forces.
Where is the magnetic field strongest on a magnetic?
The north and south poles
If the forces on a moving object are balanced, the object will continue …
To move in the same direction at the same speed.
What is Newton‘s 2nd Law of Motion?
An object with smaller mass will go faster than an object with a larger mass if the same force is applied.
What is Newton’s 1st Law of Motion?
An object in motion will remain in motion (An object at rest will remain at rest)
Which of Newton‘s 3 Laws of Motion best describes when a person jumps off a diving board, and the diving board pushes them upward into the air?
Rubbing your hand together to generate warmth demonstrates….
Friction

1st
What is force?
A push or pull of an object.
What happens when you push a heavy box with more force?
It goes faster.
Which force keeps objects on the ground?
Gravity
Would a box with a larger mass move faster on a bumpy dirt trail or a polished marble floor? Explain why.
Marble floor - less friction
