The combining of forces when two or more forces act on an object
the push or pull that one object exerts on another
forces that are equal in size and opposite in direction
forces that are not equal in size and opposite in direction
- 4. Multiple Choice

- 5. Multiple Choice
Forces can cause a change in an object's motion
True
False
- 6. Multiple Choice
What kinds of forces change an object's motion?
Friction
Air resistance
Gravity
All of the above
- 7. Multiple Choice
What factors does friction depend on?
The roughness of the surface
The greater the force pushing the two objects together
The greater the surface area of the two objects touching
all of the above
- 8. Match
Match the following
Newton's 2nd Law
An object will move at constant velocity until a net force acts on it
Newton's 1st Law
A net force acting on an object causes the object to accelerate in the direction of the net force
Law of Conservation of Momentum
Every action as an equal and opposite reaction
Newton's 3rd Law
All moving objects have momentum. Momentum is transferred between objects in a collision
- 9. Match
Match the following types of frication
Static Friction
Forces between two surfaces that are NOT moving past each other
Sliding Friction
Force between two surfaces that are sliding past each other
Rolling Friction
Force between a rolling object and the surface it rolls on
- 10. Drag and Drop
Newton's 1st law is also known as the Law of (a)
Inertiamomentumfrictionair resistance - 11. Multiple Choice
The tendency of an object to resist a change in motion is called...?
friction
air resistance
inertia
gravity
- 12. Multiple Choice
Air resistance can be determined by.....
Speed
Size
Shape
All of the above
- 13. Multiple Choice
The Law of Universal Gravitation is
any two masses exert an attractive force on each other
the force that causes all falling objects to have an acceleration of 9.8 m/s2

- 14. Multiple Choice
The law of universal gravitation depends on what 2 things?
mass
velocity
distance
acceleration
- 15. Multiple Choice
Is there any acceleration in terminal velocity?
Yes
No
- 16. Drag and Drop
