an object changing position over time; change in position is measured by distance over time
What is motion?
100
The laws of motion are named after this person
Who is Isacc Newton?
100
force that resists motion between two touching surfaces; slows things down and can also produce heat; acts in the opposite direction of force
What is Friction?
100
cars, roller skates, wagons, door knobs, and gears
What is Wheel and Axle?
200
force that brings objects toward earth
What is gravity?
200
rate of increase of speed or velocity
What is acceleration?
200
the tendency of an object to resist a change in motion or keep doing what it is doing
What is inertia?
200
force pushing against the motion of an object
What is resistance?
200
ramp, slanted road, path up a hill, or slide
What is inclined plane?
300
an object remains in place, no movement occurs
What is balanced force?
300
force of speed of movement; mass in motion
What is momentum?
300
this law says an object tends to stay at rest and an object tends to stay in motion with the same speed and in the same direction unless acted on by an unbalanced force
What is Newton's First Law of Motion?
300
stored energy
What is potential energy?
300
used to push objects apart; fork, ax, knife
What is a wedge?
400
motion occurs; the movement goes in the direction of the greater force
What is unbalanced force?
400
distance divided by time. Example: 25MPH
What is Speed?
400
This law states acceleration is always in the direction of the unbalanced force
What is Newton's Second Law of Motion?
400
energy of motion
What is kinetic energy?
400
hammer, bottle opener, crow bar
What is a lever?
500
the way the force is applied determines the way an object moves
What is direction?
500
speed with direction
What is Velocity?
500
This law states for every action, there is an equal and opposite reaction
What is Newton's Third Law of Motion?
500
something in an experiement that can be changed
What is a variable?
500
flag pole, clothes lines, blinds, mechanical cranes
