Vocabulary
A push or a pull
What is Force?
Who is the physicist who established the laws of motion?
Isaac Newton
What will fall faster: a glass marble or a balled up piece of paper?
Marble
An object in motion stays in motion unless acted upon by an unbalanced force
Newtons 1st Law
An objects tendency to resist change
Inertia
Show an example of an incline plane.
All points if it has a sloping surface.
What will roll faster: a ball on an inclined plane, or a ball on a flat table?
The inclined plane
The heavier an object the more force you need
Newtons 2nd law
A simple machine consisting of a sloping surface
Incline Plane
As you stand on the ground, your body push on the earth with a force, and the earth reacts on your body with the same force in opposite direction. What is this an example of?
Newtons 3rd Law
Which will reach the bottom first: a ball on a curving slide or a ball on a straight slide?
Straight Slide
What is the second half of newtons 1st law?
An object at rest stays at rest unless acted upon by unbalanced force.
The resistance that one surface or object encounters when moving over another
Friction
A ball rolling down a hill will continue to roll unless friction or another force stops it. What is this an example of?
Newtons 1st Law
Which surface provides more friction: a table top or grass?
Grass
Show an example of newtons 2nd Law.
All points if they show an object without weight and the force it takes to move it, then add more weight and move the same object with more force.
For every action (force) in nature there is an equal and opposite reaction.
Newtons 3rd Law
The distance traveled over a period of time.
What is Velocity?
Does a ball roll farther on the cement or the sand?
Cement, extra 100 points if they say why and mention the word friction.
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object
Newtons 2nd Law
