Forces and Motion PartII
Simple Machines
100
A point that is assumed to be at rest and is needed to describe the motion of objects.
What is reference point?
100
A push or a pull
What is force?
100
A force that opposes the relative motion of two surfaces. (A book sliding across a table.)
What is friction?
100
A machine that uses only one movement.
What is a simple machine?
200
The distance traveled divided by the time it takes to travel the distance.
What is speed
200
Th combination of all the forces acting on an object.
What is net force?
200
Using a magnet to pick up a paper.
What is non contact force?
200
A push or a pull that one object places on another.
What is a force?
300
The change in velocity divided by the time neededfor the change to occur.
What is acceleration ?
300
When an object has a net force of 0 and is not moving.
What is balanced forces?
300
The pull that every object has on every other object due to their masses. (Earth has this, it keeps you grounded.)
What is gravitiy?
300
An object like a wheel, that has a rope or cable running through it.
What is a pulley?
400
The speed of an object and its direction of motion.
What is velocity?
400
When an object resists a change in motion. (not moving or at rest)
What is inertia?
400
When the motion of an object changes, it has this type of force
What is unbalanced forces?
400
A rod or plank that pivots about a fixed point.
What is a lever?
500
A car driving down the street is an example of this.
What is motion?
500
When two objects are touching each other. (your hands on a your textbook)
What is contact force?
500
When you stand on a scale, you are measuring the strength of this gravitationlforce.
What is weight?
500
A flat sloped sureface. (Ramp)
What is an inclined plane?
