An object that slows down is decelerating |
|
What does decelerating mean? |

|
The acceleration of an object can be calculated from the gradient of a velocity?time graph. |
|
How can the acceleration of an object be calculated from a velocity-time graph? Link back to RP19 (f=ma) using light gates.
Change mass of trolley on air track. record effect on acceleration. Calculate using the SUVAT equation |

The following equation applies to uniform acceleration:
final velocity 2 ? initial velocity 2 = 2 ? acceleration ? distance
v2 ? u2 = 2 a s
final velocity, v, in metres per second, m/s initial velocity, u, in metres per second, m/s
acceleration, a, in metres per second squared, m/s2 distance, s, in metres, m |
|
What equation applies to uniform acceleration and what are the units involved? |
|
|
|
Near the Earth?s surface any object falling freely under gravity has an acceleration of about 9.8 m/s2. |
|
What acceration does an object falling freely under gravity, near the Earth?s surface any object have? |
