How is speed different from velocity?
What is velocity has direction

If a car is driving on a racetrack and takes the curve maintaining its speed of 120 mph, is it accelerating? and why?
Yes, because its a change in direction

What is the formula for calculating force?
F=MA
200
what does a distance / time graph tell us?
speed
300
What is a change in speed called?
What is acceleration?

What are three ways you can tell if something is accelerating?
What is speed up, slow down, change directions

If I push the car with 20N of force left and you push the car with 10N of force left, calculate the net force on the car with direction.
What is 30N left

If I have an object with 2kg mass and the acceleration is 4 m/s/s, what is the force?
8 N
300
If I see a distance/time graph and it has a line that looks like a roller coaster, does it mean the car was driving up and down hills?
No, it means the speed was increasing and decreasing
400
If I show you a picture of a speedometer at 65 mph, does it tell you speed, velocity or acceleration?
What is speed
400
If I leave my driveway and drive 30 mph straight down Wesley to wal mart, I stop at a stoplight, then turn left into wal mart parking lot. How many times did I accelerate in the story?
What is 3
400
If you push a box with 10N of force right and I push it with 5N force left, calculate the net force with direction.
What is 5N right
400
If I have an object accelerating at 6 m/s/s and it has a 3 kg mass, what is the force?
18 N
400
How do you find average speed?
add up all of the speeds and divide by the number of speeds
500
What do speed and velocity have in common?
They both tell you how fast an object is moving.
500
When an object is acted on by unbalanced forces it will always....
What is accelerate
500
What are units of force measured in?
Newtons
500
If I'm pushing you in a chair, and I stop pushing, eventually you will stop. What force causes you to stop?
Friction
500
how does mass affect speed?
the greater the mass the more force you need to accelerate
