when an object changes its position
Motion
an indicator that orients you; the place from which you measure, record, or witness an event
Reference point
how far an object has moved
Distance
distance and direction of an object’s change of position; difference in starting and ending point
Displacement
the distance an object travels per unit time
Speed
total distance traveled divided by total time traveled
Average speed
speed at a given point in time; this is what is shown on a speedometer
Instantaneous speed
speed of an object and the
direction of its motion
Velocity
rate of change of velocity; object changes its speed, direction, or both
Acceleration
A push or pull one body exerts on
another
Force
Sum of all of the forces that are acting on an object
Net force
the tendency of an object to resist a change in its motion. Inertia depends on mass. Increase mass, Increase inertia
Inertia
a force that resists a change in motion caused by two objects in contact with one another
Friction
force that opposes the motion of objects that move through the air. Caused by size, shape, and speed
Air resistance
attractive force between two objects that depends on mass and distance between objects
Law of Universal Gravitation
force that depends on gravity
gravitational force exerted on an object. W = F =ma = m (9.8)
Weight
momentum is not gained or lost during a collision - it is transferred
Law of Conservation of Momentum
First law nickname?
Law of inertia
Second law formula?
F=ma
Third Law nickname?
Law of action and reaction
