1
Q
how do we calculate speed?
A
distance traveled (meters)
---------------------------------------------
time taken (seconds)
2
Q

Q
acceleration is change of what per second?
A
velocity.
4
Q
the formula for acceleration is known as what?
A
time taken
5
Q
deceleration is what?
A
the change of velocity per second when an object slows down.
6
Q
if a velocity time graph is a horizontal line the acceleration what?
A
acceleration = zero
7
Q
the gradient on a velocity - time graph represents what?
A
acceleration
8
Q
the area under the line on a velocity-time graph represents
A
distance traveled.
9
Q
