Distance eon graphs
The speed of an prey is the outmatch traveled each s < the slope of the breeze on a distance time graph represents the speed.
* If an object is stationary, the line on a distance time graph is horizontal.
* if an object is pathetic at a eternal speed, the line on a distance time graph-time graph is a straight line that slopes upwards
Speed in metres per certify, m/s = distance travelled in metres, m
time taken in seconds, s
fastness and acceleration
Velocity is speed in a presumption direction
acceleration is the change of velocity per second
Acceleration- positive
Deceleration - negative
If the velocity of an object changes we enunciate that it accelerates.
Acceleration = V-U
T
Acceleration = V-U
T
Acceleration is measured in metres per second m/s2
v is the final velocity in metres per second m/s
u is the initial velocity in metres per second, m/s
t is the time taken for the change in seconds, s
Velocity time graphs
* If the line on a velocity time graph was horizontal, the acceleration is zero. This means the object is travelling at a steady speed/ constant velocity.
* The gradient of a velocity time graph represents acceleration.
* The reach under the line on a velocity time graph is the distance travelled.
Using graphs
* The speed of an object is given by the gradient of the line on a distance time graph
* The acceleration of an object is given by the gradient of the line on a velocity time...If you want to permit a full essay, order it on our website: Ordercustompaper.com
