Motion 1
The change in the position of an object is known as this.
Displacement
What is a car doing if on a velocity-time graph it is a straight line down?
slowing down
If Joe runs 4 miles in 1 hour and Bob runs 2 miles in 20 minutes, who is faster?
Bob is faster
Displacement is this type of substance.
vector
Motion of a car if the line on the distance-time graph is horizontal.
Not moving
Acceleration that does not change in time is called this.
Constant acceleration
The starting point you choose to describe the location, or position, of an object.
reference point
Wha is the acceleration of a car traveling at 10 meters per second that takes 20 seconds to stop?
0.5 m/s2
The slope of a velocity vs. time represents this.
acceleration
The metric units for distance and displacement
meter
The amount an object moves is known as this.
Distance
A pencil's ______ might be described as 3cm to the left of the stapler.
position
This is where an object is located
position
The rate of change in velocity is known as this.
average acceleration
Acceleration is calculated using this equation.
change in velocity over time
The magnitude of an object’s motion with regard to its direction is this.
Velocity
The velocity of an object at any given time is known as this.
instantaneous velocity
What do you have to do to pay a test?
study
Motion of a car if the line on a distance-time graph is curving upward.
Speeding up
The distance an object moves in a unit of time.
Speed
The magnitude of an object’s motion with no regard to direction is this.
Speed
