Newton's 1st Law
An object at _____ stays at rest and an objection in motion stays in ______ .
Rest, Motion
This describes Newton's 1st Law of Motion
Inertia
Mass is how much an object weighs
False
Force = Mass x _______
Acceleration
For every ______, there is an equal and opposite _______.
Action, Reaction
Inertia is the resistance to ______ in the motion of the object
Change
Gravity depends on these two factors
Mass and Distance
There is no weight in gravity.
False
If force decreases, acceleration ______.
Decreases
This law states that the forces are equal and opposite. What type of force is this?
Balanced force
An object at rest measures a velocity of _____.
0
This term is the gravitational force exerted on an object
Weight
Force is required for an object to be in motion or at rest.
True
Newton's Second Law of Motion states that an object's _________ is in the same __________ as the net force on the object .
acceleration, direction
Why is jumping on a trampoline an example of Newton's 3rd Law of Motion?
You exert a force and the trampoline exerts an equal and opposite force on you.
A bowling ball has more mass than a golf ball, so the bowling ball will have more _____ according to Newton's First Law of Motion
Inertia
The maximum speed that a falling object reaches
Terminal Velocity
Force, Velocity, and Mass are related
True (Remember acceleration is the change in velocity!)
If you throw a softball and a baseball as hard as you can, they don't have the same speed due to _____.
Different masses
Why is gravity an example of Newton's 3rd Law of Motion?
Just as the Earth pulls down on an object with a force, objects also pull on the Earth.
In order to change an object's motion, what is required?
Force
Two surfaces that are not moving past each other have _____.
Friction or Static Friction
False (Horizontal and Vertical)
What is the net force on a sky diver falling with constant velocity of 10 m/s downward?
0 (if velocity is constant, acceleration is 0)
If the forces are equal and opposite according to Newton's 3rd Law of Motion, what causes motion for these objects?
The force pairs do not cancel, however, because they act on different systems.
