Motion 1
The distance and direction of an object from its starting position.
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
The amount of matter found in an object
Mass
Motion of a car if the line on the distance-time graph is horizontal.
Not moving
Acceleration where an object is slowing down.
negative acceleration
What is Nikki's total displacement if she drives 4 miles east from her house to pick up her friend Dave, and then drive 2 more miles east to school?
6 miles E
What 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
The acceleration due to gravity is commonly represented using what variable?
g
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 is the acceleration of gravity on planet Earth?
9.8 m/s2
Motion of a car if the line on a velocity-time graph is going upward.
Speeding up
The slope of a distance vs. time graph represents this.
velocity
The magnitude of an object’s motion with no regard to direction is this.
Speed
The units for acceleration are this.
m/s2
A graph that can help you predict the velocity of a moving object.
Distance-Time Graph
What is Johnny's total displacement if he walks 2 miles to the school, and then takes the short cut back home that is only 1 mile?
zero
The SI unit representing speed or velocity
m/s
