Friction
What does friction do
acts against motion when two surfaces rub past each other
Newton's first law is also known as what
Inertia
whats another word for motion?
moving or movement
How far you are from where you started
Displacement
What does speed mean
how fast you are going
What type of friction keeps stationary objects from moving
Static friction
Finish the law. An object in motion stays in motion until acted upon- an abject
at rest stays at rest until acted upon
The downward force that keeps things from floating away
Gravity
How far you traveled, even if you end up back where you started
Distance
left, right, up, down
North, south, east, west a
are all examples of what
Directions
Sky diving is an example of what kind of friction
Fluid friction because the surface area of the diver changes
the force needed to move an object is equal to
the mass of the objet time the acceleration
word that means how much motion something has
Momentum
What is the distance of a person who started at home and then walked 2 miles to get to school
2
How fast was someone going of they go a distance of 60 miles in 2 hours
30mph
kinetic friction acts on objects that are doing what?
moving
Newton's third law of motion states
Every action has an equal and opposite reaction
Word that means a change in speed and or direction
Acceleration
What is the displacement of a person who goes miles to get to the store and then walks 2 miles to get back home
0 displacement
4 distance
how long did it take someone to get 100 miles is they are traveling at a speed of 50mph
2 hours
Applying the breaks onto you bike tires is what kind of friction
Kinetic friction
a bowing ball going down an ally is a good example of which of Newton's laws?
Newton's first law- Inertia
Word that means speed with direction/displacement
Velocity
What is the distance and displacement of someone who started at home, walked 3 miles to the right and then 5 miles to the left
Displacement 2
Distance 8
Speed needs what two factors
a time and a distance like 35MPH
