Basics
editSUVAT is a collection of all of the letters used for variables in basic motion equations.
The equations you'll need
editThese are the equations you need to know:
If you were to plot a distance time graph, the gradient would be velocity. If the graph is curved, it shows that there is a change in velocity and the object is accelerating
If you were to plot a velocity time graph, then the area under the graph will represent the displacement, while the gradient of the line represents acceleration. A straight line represents constant acceleration whilst a curved line shows acceleration is changing
If you were to plot an acceleration time graph, then the area under the curve will represent the velocity.
Example question and answer A car is in a drag race, the race is 1000m (1km) and the driver accelerates with a constant acceleration and finishes the race in 40sec. 1. What's the acceleration of the car? 2. What's the final velocity of the car when it finishes? Answer:
1. Finding :
2. Finding :

Vector quantities
editWhat's a vector? In one sentence, a vector is a quantity with a magnitude and a direction.
Note, that if you want to find either the displacement, speed or acceleration as a number, then you'll need to find the magnitude of the vector, follow these respectfully:
