This tells us the speed of an object (hint: think of graphs)
What is slope of a distance-time graph

The acceleration directed toward the center of a circular path.
What is centripetal acceleration
200
The three types of force
What is balanced, unbalanced, and net
200
Found from the slope on a velocity-time graph
What is acceleration
300
How far an object moved from its original position and in what direction
What is displacement

Trying to get away from her pesky brother, Amanda runs a distance of 23 m in 6 s. What is her velocity?
Answer: 3.8 m/s

A man is walking by the zoo at a speed of 4 m/s. Suddenly, a loose tiger starts chasing him! He speeds up to a speed of 15 m/s in 2 and 1/2 s. What is his acceleration?
Answer: 4.4 m/s/s
300
This force opposes motion.
What is friction
300
Shown by a negative slope on a velocity-time graph
What is deceleration or negative acceleration
400
The distance traveled divided by the time interval during which the motion occurred
What is speed

Tracy is trying to catch the bus. She runs at a speed of 8.5 m/s in 16 s. How far did she run?
Answer: 136 m

A car starts from rest and accelerates to a velocity of 80 m/s after traveling 6.25 s. Find its acceleration.
Answer: 12.8 m/s/s

If gravity is pulling down on an object, an equal force is pulling up on the same object, and another force is pushing the object right, what direction will the net force be in?
Answer: To the right
400
This is shown by a straight line with a constant slope on a distance-time graph.
What is constant speed
500
The rate at which an object's velocity changes over time
What is acceleration

How long would it take Jackie to run a 5K marathon at a speed of 7.3 m/s? (hint: 5K means 5 km - you should first convert km to m)
Answer: 684.9 s

Sally is driving to the bank at a speed of 100 m/s. Out of no where, a group of ghastly and apalling robbers runs up to her car. She slows down so she won't hit them to a speed of 33 m/s. All of this happens in a measly 4.6 s. What is Sally's acceleration?
Answer: -14.6 m/s/s

What is the acceleration of an object that has a force of 165 N and a mass of 25 kg?
Answer: 6.6 m/s/s
500
This slope shows an object speeding up on a velocity-time graph.
