Mrs. Vaughn drove west 17 miles to the store. Then, she drove 2 miles east to the gym. what distance did she drive?
An object that changes position relative to a reference point is
in motion
On a distance vs. time graph of an object’s motion, distance is usually
Average speed can be represented by the mathematical expression
Average Speed = Distance /Time
A baseball is pitched with a speed of 55 m/s. How long does it take the ball to travel 21 m from the pitcher’s mound to home plate?
A cross-country runner runs northwest 6.2 km/hr in 1.5 hours. What is his distance
A deer can run a distance of 174 m in 4.65 s at its top speed. What is the deer's top speed?
return to start
acceleration or speeding up
deacceleration or slowing down
constant speed
constant speed
acceleration or speeding up
deacceleration or slowing down
at rest or stationary
Match the graph to the description:
"The car is traveling at a constant speed."
Segment O-A: The bus is _________________. It's speed changes from 0m/s to 10 m/s in 5 seconds.
accelerating
decelerating
constant speed
at rest
The equation for finding average acceleration for straight-line motion is
average acceleration = (vf - vi) / t
average acceleration = vf / t
average acceleration = (vi + vf) * t
average acceleration = vf + vi
What happens when a car slows down and velocity changes?
The difference between speed and velocity is that velocity includes
When centripetal acceleration occurs, an object
is changing directions
A 71 kg skater pushed by a friend accelerates 3.5 m/sec2. How much force did the friend apply?
What is the mass of a ball that has a force of 17 N and an acceleration of 5.5 m/s(squared)?
What is the momentum of a 15,000 kg box car at rest?
Name the missing force.
Weight force
Normal force
Frictional force
Tension force
What is the NET FORCE of this diagram?
17 N, right
17 N, left
23 N, right
12 N, up

Never
You are carrying a lunch tray when you bump into the edge of a table. Although the tray did not tip, your milk falls off the front of the tray.
Newton's 1st Law of Motion
Newton's 2nd Law of Motion
Newton's 3rd Law of Motion

the combination of all forces acting on an object
objects momentum is determined by the
how does total momentum before and after a collision compare
the law that states unbalanced forces acting on an object equals the objects mass times its acceleration
