Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.

Learn and revise motion in a straight line, acceleration and motion graphs with BBC Bitesize Combined Science AQA Synergy study guide.

Derivation Of First Equation The first equation can be derived using a velocity-time graph for a moving object with an initial velocity of u, final velocity of v and acceleration of a.

Today, you learned that when an object is in uniform circular motion, its velocity is tangent to the circle and its acceleration is pointing inward.

For uniform motion, acceleration is zero and the x-t graph is a straight line inclined to the time axis and the v-t graph is a straight line parallel to the time axis.
