It demonstrates the measurements to take to calculate velocity and acceleration. Students could be asked to predict the effect of increasing mass and increasing force on acceleration of an object.

Measuring mass accurately can be crucial in some cases, like calculating how much fuel you need in an airplane. Mass and weight should not be confused—weight depends on the force of gravity, but ...

Newton’s Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” ...

For National 4 Physics describe and examine the motion of a moving object, calculating acceleration, distance and average speed.
