Definintions
How far an object has moved
Distance
Speed =
Distance/time
The slope of a position time graph
ANSWERS: SPEED, VELOCITY
You ride your bike for a distance of 30 km. You travel at a speed of 0.75 km/ minute.
How many minutes does this take
40 MINUTES
where IS THE OBJECT MOVING AT ITS FASTESTSPEED
A
Change in speed over time
Acceleration
Time x speed =
Distance
Acceleration is shown by the slope of what graph
Velocity vs time
Speed vs time
A person in a kayak paddles down river at an average speed of 10. km/h.
After 3.25 hours, how far has she traveled?
32.5 KM
Acceleration is negative
Speed
distance an object travels per unit of time
DISTANCE / SPEED=
TIME
Where is the object slowing down
C
A car starting from rest accelerates at a rate of 8.0 m/s. What is its final speed at the end of 4.0 seconds?
32 m/s
Coordinates (?,?)
(x,y)
TOTAL DISTANCE / TOTAL TIME
AVGERAGE SPEED
Acceleration =
(V final - V initial) / time
where IS THE OBJECT ACCELERATNG AT A SLWOER SPEED
D
2.6 seconds
What is the difference between Velocity and speed
Velocity can be negative - vector
speed can not - scalar
Speed of an object and its direction of motion
Displacement =
Final positions - Initial position
wHERE IS THE OBJECT MOVING AT A CONSTANT SEED
B
An arrow moving at 35m/s and travels for 5 seconds. How far does the arrow travel?
175 meters
. Imagine a basketball bouncing. As it is moving up, it has_________
NEGATIVE ACCELERATION
