Success Criteria:
I am able to calculate the velocity of an object from the gradient of its position-time graph
I am able to determine displacement of an object by calculating the area under a velocity-time graph
I am able to calculate the acceleration of an object from the gradient of its velocity-time graph
Fun Fact
The fastest land animal, the cheetah, can accelerate from 0 to 97 kilometers per hour in just a few seconds. This incredible acceleration allows the cheetah to reach its top speed of around 113 kilometers per hour in short bursts, making it the fastest accelerating and fastest land mammal on Earth!
Key terms
Position-Time graphs show the position (x) of an object at any time (t). The gradient of a position-time graph is the velocity of the object.
Velocity-Time graphs show the velocity (v) of an object at any time (t). The gradient of a velocity-time graph is the acceleration of the object.
Displacement can be calcutated from the area of a velocity-time graph. Area under the time axis must be calcuated as negative, as this represents the motion of the object being in a negative direction.
Acceleration-Time graphs show the acceleration (a) of an object at any time (t). The area under an acceleration-time graph is the change in velocity of the object in that time interval.
