Transcript of Acceleration

Aim
To know how to calculate acceleration
To know how to spot acceleation/deceleration in distance and speed/time graphs
Starter
A snail moves 5 metres in 2 hours.
If the snail moves at the same speed calculate:
(a) the time it takes to move 20 m
hours
(b) the distance it would move in 3½ hours
metres
(c) the time it takes to moves 1 m
minutes
Acceleration
Acceleration is the rate at which an object changes its speed. It's calulated using the equation: acceleration = change in speed / time taken.
Speed-time graphs illustrate how the speed of an object changes over time. The steeper the gradient of the line, the greater the acceleration.
Calculating acceleration
acceleration = change in speed / time taken


Example
A bus accelerates from 5 m/s to 25 m/s in 10s
Calculate its acceleration....
Acceleration 2
In everyday language we use 'accelerate' to mean speeding up and 'decelerate' to mean slowing down. In scientific terms 'acceleration' is the rate at which something changes its speed - faster or slower.
Acceleration depends on two things:
How much the speed changes
How much time the change in speed takes
Acceleration
