How many of Newton's Laws have we discussed in class?
3
The force that slows down a moving object is called _____.
Newton's 1st Law of Motion states that an object in motion stays in motion OR an object ___ ____ ____ ___ ____.
at rest stays at rest
If a box sits motionless on the floor, it has _______ forces.
Balanced
This is an object's resistance to changing direction.
This is the math formula for speed
Distance รท Time = Speed
This is an increase in an object's speed.
Acceleration
This law states that for every action there is an equal and opposite reaction.
Newton's 3rd Law of Motion
For an object to move, the forces need to be _______.
Unbalanced
The change in position of an object due to forces
Motion
The speed AND direction an object is moving is called _____.
velocity
This is a decrease in an object's speed.
Deceleration
Newton's 2nd Law of Motion states that this is needed to move an object with a larger mass.
a larger force
What is 12 x 15?
180
What is the energy of motion?
Kinetic energy
This is the mathematical formula for Newton's 2nd Law of Motion that states a larger force is needed to move an object with a larger mass.
Force = mass x acceleration or F = ma
Warming my hands by rubbing them together is an example of this type of friction.
Sliding friction
An object moves because the forces are ______.
Unbalanced
This is the formula for Newton's 2nd Law of Motion.
Force = Mass x Acceleration
This type of friction is created when a moving object travels through a liquid or water.
Fluid friction
Which of Newton's Laws states that more force is needed to move a car than a lawn mower?
Newton's 2nd Law of Motion
This type of friction is created when an object moves through air or a liquid. An example would be a swimmer moving through water.
Fluid friction
