In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...

When an object does not start at rest, you need to measure both the initial velocity and the final velocity to be able to calculate the acceleration. One way to to do this is to use a double mask. A ...

In this case on an object on a slope, the weight is a single force that can be resolved into two independent components: A 10 kg box slides down a frictionless slope. The slope is at 30° to the ...
