The motion of objects can be analysed using equations and graphs. These tools allow other aspects of motion such as acceleration and displacement to be determined or modelled.

Projectile motion describes how objects move through the air after being launched, like when a ball is thrown or an arrow fired. After launching, the only force acting on the projectile is gravity ...

Velocity-time graphs If an object moves along a straight line, its motion can be represented by a velocity-time graph. The gradient of the line is equal to the acceleration of the object.
