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

Constant Acceleration We are going to measure distance and time for an accelerating object and use that to find the acceleration. In the past, I would do this lab using a specialized drop timer.

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 ...

If the velocity-time graph is curved, the acceleration can be found by calculating the gradient of a tangent to the curve.

Acceleration and velocity Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate.

Air resistance is a force that depends on the velocity. This means that the force (and thus the acceleration) is not constant. That's a big problem. We can still solve this with a numerical ...
