____ equals the distance traveled divided by the amount of time it takes to travel that distance.
What is average speed
100
His greatest discoveries of how forces cause motion, could explain the motion of objects using a set of principles
What is NEWTON'S LAW OF MOTION
100
The SI unit of measurement of force
What is Newtons (N)
100
m/s ^2
which means meters/ (seconds x seconds)
What is Acceleration SI units
100
d
s= t
What is Average speed equation
200
an object is the speed of an object and its directions. It changes when the speed changes, the direction of motion changes, or both change.
What is VELOCITY
200
an object will not change its motion unless an unbalanced force acts upon it. For example, an object that is not moving, like a book sitting on a table, remains at rest until something pushes or pulls it.
What is Newtons First Law
200
TRUE or FALSE: a force can cahnge the direction of an objects motion
What is TRUE
200
Rough Surfaces
What is a decreasing factor for friction
200
Distance traveled= average speed x time
d=st
What is Distance Equation
300
Acceleration
What is the change in velocity divided by the time needed for the change to occur.
300
If a moving object should never slow down or change direction until a force is exerted on it, what is the force that is acting upon it called...
What is friction
300
TRUE OR FALSE: Anytime an objects speed, or direction of motion, or both change, a force must have acted on the object.
What is TRUE
300
what is a simple machine: wedge, inclined plane, pulley, or lever?
What is all of them, because a simple machine uses only one movement
300
Average Speed= distance traveled / time
What is Speed Equation
400
is a push or pull (measured in NEWTONS **N)
What is force
400
Explains how a net force acting upon an objet changes the motion of the object. A net force changes the velocity of the object and causes it to accelerate. If an object is acted upon by a net forc, the acceleration of the object will be in the direction of the net force, and acceleration equals the net force divided by the mass...
What is Newtons Second Law
400
An attractive force between any two objects that depends on the masses of the objects and the distance between them
What is Gravity
400
an object, like a wheel, that has a groove with a rope or cable running through it.
What is a Pulley
400
final speed - initial speed / time
What is Acceleration Equation
500
tendency to resist a change in motion
What is INERTIA
500
Newtons Third Law
What is One object exerts a force on a second object, the second object exerts an equal force in the opposite directionon the first object. (EX. Walking on the sidewalk- you pushing down on it and it pushing back on you)
500
If you and a friend push on a door, yet on opposite sides and using the same force does the door move? Why?
What is No it does not move because there are equal forces pushing on the door in opposite directions causing no movement (balanced Force)
500
If you and a friend are pushing a basketball cart, and both are on the same side, the cart will move because of the unequal forces (not canceling them out), what is another name for this?
