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. Describe the motion of the ...

Speed-time graphs are very useful when describing the movement of an object. This is a velocity time graph of an object moving in a straight line due North. The displacement of this object is the area ...

One must get the methods of measuring position and time working together if we are to obtain a reliable representation of motion. To that end we have developed a unique system composed of elements ...

Your everyday notion of forces probably includes pushing and pulling and similar actions. Technically, when something is pushed or pulled we say that "a force is applied to the object". What happens ...
