Forces and acceleration are no different ... Instead of just calculating the required force, I want to make a graph. What could I plot that would produce a linear function? No—it's not force ...

Let's try making a graph. I am going to use plotly ... then you can detect the frictional force. Why? Because the up acceleration should be different than the down acceleration.

Students could be asked to predict the effect of increasing mass and increasing force on acceleration of an object. This film highlights the sketch graphs generated in these investigations.

Save guides, add subjects and pick up where you left off with your BBC account. The gradient of a velocity-time graph at a particular time gives the acceleration of the object at that time.

The amount of the force and the location where it is providing the push can change either or both the speed (the magnitude part of acceleration) and direction. Now that we know how a massive body ...
