physics chapter 4
acceleration
the increase of speed per second
acceleration (accelerating motion)
a movement in which the speed keeps increasing
deceleration
the reduction in speed per second
(displacement, time) diagram
a graph showing the position against the time taken. this is also called an (x,t) diagram
(speed, time) diagram
a graph showing the speed against the time taken. this is also called a (v,t) diagram.
uniform acceleration
a movement in which the speed is increasing at a steady rate
uniform deceleration
a movement in which the speed is decreasing at a steady rate
uniform motion
a movement in which the speed remains constant (does not change)
(v,t) diagram
a graph showing the speed against time taken. this is also called a (speed , time) diagram
(x,t) diagram
a graph showing the position against the time taken. this is also called a (displacement, time) diagram
