Newton's Laws of Motion Test Review
Question | Answer |
---|---|
"An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force." | Newton's First Law of Motion |
Who is the 17th century scientist who put forth a variety of laws which explain why objects move (or don't move" as they do?) | Sir Isaac Newton |
How many laws of motion did he create? | Three |
All objects ______ changes in their state of motion. | Resist |
Newton's first law of motion is also called the Law of ________. | Inertia |
It is the natural tendency of objects to _____ on doing what they're doing. | Keep |
Force = Mass x Acceleration this is ... | Newton's Second Law of Motion |
An object will _____ in the direction you push it. | Accelerate |
If you _____ it twice as hard, it accelerates twice as much. | Push |
If it has twice the _____, it accelerates half as much. | Mass |
"For every action there is an equal and opposite reaction", this is ... | Newton's Third Law of Motion |
This means that for every force there is a reaction force that is _____ in size, but opposite in direction. | Equal |
That is to say that whenever an object pushes another object it gets pushed back in the _____ direction equally hard. | Opposite |
"If you _____ on it, it pushes on you!" | Push |
Push or Pull | Force |
Pull | Gravity |
Resistance to change | Inertia |
A force of resistance between two objects | Friction |
Speed of an object, but in a specific direction | Velocity |
Amount of matter in an object | Mass |
Distance traveled per unit of time | Speed |
Measure of graviational attraction or force/amount of mass | Weight |
