Gravity
Mass
What is a force?
The amount if matter in an object
The amount of mass in an object
A push or pull acted on an object.
What is gravity?
A downward force only
A force that pulls two objects together
A contact force is from
objects physically touching
far apart objects
not touching object
always a pull

50 N to the left
50 N to the right
200 N to the left
200 N to the right
What is the net force on the car?
400 N forward (left)
0 N (balanced forces)
200 N forward (left)
200 N backward (right)
What effect does friction have on a moving object?
it causes the moving object to slow and eventually stop
it causes the moving object to speed up
it keeps the moving object moving in the same direction forever
it causes the moving object to turn around and move in the opposite direction

This motion graph represents:
constant speed
acceleration
body at rest
slowing down
A force that opposes motion is
friction
inertia
acceleration
momentum
A change in an object's position, direction or location
Position
Force
Motion
Inertia
Equal forces that do not cause a change in an objects motion
Unbalance force
Push or a pull
Balanced force
Average speed
Are unequal forces that cause a change in the motion of an object
Balanced forces
Unbalanced forces
Inertia
Gravity
AN OBJECT WILL HAVE A TENDENCY TO RESIST CHANGE IN MOTION. THIS PROPERTY IS PROPORTIONATE TO THE OBJECT'S MASS.
INERTIA
FORCES
NET FORCE
APPLIED FORCE
IF A CAR IS AT REST, AND THE CAR REMAINS AT REST, THIS WOULD BE AN EXAMPLE OF __________
FRICTION
MAGNITUDE
INERTIA
NET FORCE
MOTION OCCURS WHEN AN OBJECT _______
IS DIRECTLY PROPORTIONAL TO ITS MASS
IS BALANCED
CHANGES POSITION
HAS A DIFFERENT FUNCTION
HOW CAN YOU TELL THAT THE DATA TABLE TO THE LEFT IS SHOWING CONSTANT SPEED.
THE DATA TABLE TO THE LEFT THE VELOCITY STARTS AT ZERO.
THE INCREMENTS OF THE VELOCITY ARE INCREASING AT A CONSTANT RATE.
THE DATA TABLE ON THE RIGHT HAS TIME MOVING AT THE FIXED SCALE.
WHICH CAR WON THE RACE AND WHY? CHOOSE THE BEST ANSWER.
CAR B WON BECAUSE IT WENT THE FASTEST.
CAR A BECAUSE HE STARTED CHEATED AND STARTED AT A CLOSER SPOT.
CAR B WON BECAUSE IT TRAVELED THE FARTHEST DISTANCE IN THE SHORTEST AMOUNT OF TIME.
CAR B BECAUSE THE SLOPE IS STEEPEST.
What two things does gravity depend on?
Mass and weight
Weight and distance
Mass and force
Mass and distance
When the net force of opposite forces is zero, the forces are
unbalanced
not equal
balanced
not even
