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

constant m is called the inertial mass of the body. We will choose to call Δ v /Δ t acceleration and give it the letter a. On the graph of velocity vs. time, Δ v /Δ t is the slope of the curve. If the ...

Constant acceleration close accelerationThe rate of change of velocity. It is measured in metres per second squared (m/s²). Acceleration = change of velocity ÷ time taken. is shown by a straight ...

Another basic question people have been asking: why do we feel acceleration, but not velocity? One person recently effectively asked this in the "Physics Is Fun" Facebook group.

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...
