Newton’s First Law
Newton's Second Law
Newton's Third Law
Forces that are equal and opposite are
Newton's First Law
Newton's Second Law
Newton's Third Law
An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by a force is
Newton's First Law
Newton's Second Law
Newton's Third Law
Why doesn’t an apple and a feather fall at the same speed?
The apple is heavier and there far falls faster
The Feather is lighter and will fall faster
Air resistance causes them to fall at different speeds
Gravity is an example of
Non-contact forces
Contact forces
Friction
When a car slows down this is an example of
acceletation
uniform motion
force
If you apply the same force two two object with different mass
The object with more mass will move farther
The object with less mass will move farther
The objects will travel the same distance
When a moving bumper car bumps into a stationary bumper car the stationary car will move. This is an example of
Newton's First Law
Newton's Second Law

electricity
How do electric and magnetic forces act on different objects?
They only pulls objects
They only push objects
The either push or pull objects
The only push and pull objects when they touch each other
What happens when an object accelerates?
Its speed or direction changes
Only its speed changes
Only its direction changes
Its speed and direction do not change
What always happens when the forces acting on an object are equal in strength and opposite in direction?
The object moves
The motion of the objects do not change
The object does not move
The object becomes heavier
What happens when two forces act on an object in the same direction?
The forces are added together
The forces cancel each other out
The forces cause friction
