Velocity
This is the rate at which an object changes position and the direction it is going
Velocity
This is the difference between our starting and ending location
Displacement
Acceleration
A vehicle travels 2345 m [W] in 315 s toward the evening sun. What is its average velocity?
7.4 m/s West
How long will it take to go 150 km [E] traveling at 50 km/hr [E]?
3 hours
What graph is used to show the velocity as the SLOPE of the graph?
Position vs time, Velocity vs time, or acceleration vs time
Position vs time
This is used to calculate speed
distance
is acceleration a vector or a scalar?
Acceleration is a vector
A roller coaster car rapidly picks up velocity as it rolls down a slope. As it starts down the slope, its velocity is 4 m/s. But 3 seconds later, at the bottom of the slope, its velocity is 22 m/s. What is its average acceleration?
6 m/s^2
If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s^2 for 3 seconds, what will its final velocity be?
160 m/s
Is Velocity a vector or a scalar? (double points if you can tell me the difference between the two)
it is a vector
I ran from my room and around the school 3 times and came back to my room, was my displacement and average velocity?
Both are Zero
What graph's slope gives the acceleration of an object?Position vs time, velocity vs time, or acceleration vs time?
Velocity vs time
A parachute on a racing dragster opens and changes the velocity of the car from 85 m/s to 45 m/s in a period of 4.5 seconds. What is the acceleration of the dragster?
-8.8 m/s^2
A motorcycle traveling at 25 m/s accelerates at a rate of 7.0 m/s^2 for 6.0 seconds. What is the final velocity of the motorcycle?
67 m/s
is 5 m/s a velocity? why or why not?
no, this is a speed, because there is no direction associated with it, this is a scalar quantity.
A bird steals Mr. Hunnicutt's sandwich and his car keys. The bird then drives his car 12 miles east and then 13.7 miles west. What is the bird's displacement while driving the car?
1.7 miles West
What is the unit for acceleration
m/s^2
A car accelerates at a rate of 3.0 m/s2 . If its original velocity is 8.0 m/s, how many seconds will it take the car to reach a final velocity of 25.0 m/s?
5.67 seconds
What distance will a car, traveling 65 km/hr, cover in 3.0 hrs?
195 km
If object A is traveling at 4 m/s and object B is traveling at 4.5 m/s and they both are traveling in the same direction, how far apart will they be after 3 seconds?
1.5 meters
The same bird from the 400 point question in the category decides to leave Mr. Hunnicutt's car and fly 3 miles north and 4 miles east, what is its displacement during its flight?
5 miles north east
A cart rolling down an incline for 5.0 seconds has an acceleration of 4.0 m/s^2 . If the cart has a beginning velocity of 2.0 m/s, what is its final velocity?
22 m/s
The final velocity of a car is 30m/s. The car is accelerating at a rate of 2.5m/s^2 over an 8 second period of time. What is the initial velocity of the car?
10 m/s
How long will it take to travel 200 000 m [N] traveling 10 m/s [N]?
20,000 seconds
