Motion
Friction
Newtons Laws
Energy
Force
100
the collision between one object and another
What is conservation momentum
100
Liquid and gases. Viscosity is how thick the fluid is
What is Fluid friction
100
F2=? Newtons F1=? Newtons Net force=? Newtons
What is F2=18 Newtons, F1=20 Newtons, Net force=2N
100
All objects are lazy
What is Inertia
100
Don't cause a change in motion, they are equal or go in different direction
What is balanced forces?
200
Mass x Velocity
What is momentum
200
push or pull of two flat dry surfaces
What is Static/sliding friction
200
An object at rest will stay at rest, and an object in motion will stay in motion
What is Newtons first law
200
A force of attraction between objects that is due to their masses.
What is Gravity
200
released energy
What is kinetic energy
300
The rate at which velocity changes
What is acceleration
300
resisting the motion when a body rolls on a surface
What is Rolling friction
300
F=M(A)
What is Newtons Second Law
300
1. Do not encounter air resistance 2. On earth all free falling objects accelerate at a rate of 9.8m/s/s
What is free falling objects
300
combination of all forces acting on an object
What is net force?
400
An object when us falling under a sole influence of gravity
What is Free fall
400
A substance to reduce friction
What is lubricant
400
For every action, there us an equal or opposite reaction
What is Newtons Third Law
400
released potential energy
What is Kinetic Energy
400
Any force that causes an object to move in a circular path
What is centripetal force?
500
the state or process of acting or doing
What is action
500
The force of air pushing against a moving object
What is Air resistance
500
example of each of newtons laws
What is: 1) when you place a book on the table it will stay on the table until you move it and if you roll a marble down a slope it will continue moving until a wall of rock encounters it 2) When you push a truck and a car with the same force the car will accelerate more because it has less mass. 3) when your sitting on a chair the chair is forcing you to stay up and you are pushing down on the chair to go down
500
stored up energy
What is Potential energy
500
Cause a change in motion, and they go in the same direction
What is unbalanced forces
