Forces
100
a long ramp
What will reduce the amount of force needed to move an object?
100
a straight line
What does a constant speed look like?
100
North at 5 m/s
What is a velocity?
100
the speed if an object travels 50 meters in 5 seconds
What is 10 m/s?
100
what is the force that slows moving objects down
What is friction?
200
the trade off for a reduce in force
What is the increase in distance needed for an effort force?
200
a flat line
What does no motion look like?
200
100 ft/s
What is a speed?
200
the speed if an object takes 100 hours to go 600 feet
What is 6 ft/hr?
200
this causes movement of objects
What are unbalanced forces?
300
the force that causes falling objects to speed up
What is gravity?
300
a line moving up on the graph.
What direction shows forward motion?
300
a change in direction, speed, or velocity.
What is acceleration?
300
the speed if an object goes 80 miles in 4 hours
What is 20 mph?
300
this will result in no motion
What are balanced forces?
400
changing the number of pullies in this way will reduce the amount of force needed.
What is increasing the number of pullies?
400
(draw a graph shaped like a J)
What does speeding up look like on a graph?
400
speed and direction
What is velocity?
400
if it takes a car an hour to go 80 miles.
What is 80 mph?
400
the force that keeps an eraser from sliding on a surface as far as a piece of ice can slide.
What is friction?
500
the type of pulley that helps reduce forces
What is a movable pulley?
500
a steep line on a graph
What does fast motion look like?
500
this constantly changes if an object is moving in a circle
What is acceleration?
500
draw a graph on the board and find the average speed 1s 3m 2s 8m 3s 9m 4s 16m
What is 3.5 m/s?
500
pulley that required the same amount of force, but changes direction of the effort force.
