Newton's second law of motion is Force = Mass x Acceleration. What this states is that the acceleration of an object is dependent upon two variables, which are the net force acting upon the object and the mass of the object.
The Indianapolis Public Library provides an example of Newton's second law in action by comparing a marshmallow to a bowling ball. It takes more strength to push a bowling ball one foot than it does to push a marshmallow one foot, which demonstrates that the heavier the object, the more force it takes to make that object speed up or slow down.Learn More
Deceleration is synonymous with slowing down or is related to the relative directions of velocity and acceleration. The meaning of the word in common language differs from its meaning in physics.Full Answer >

A toilet paper dispenser is an example of a wheel and axle. The rod that supports the roll of toilet paper serves as the axle, and the toilet paper roll serves as the wheel. Like all wheel and axle machines, the toilet paper rotates concentrically around the cylindrical holder, which is fastened in place.Full Answer >
The formula for acceleration is given as a = (v2 - v1) / (t2 - t1), where "a" denotes the acceleration, "v2" indicates the final velocity, "v1" represents the initial velocity and "t2 - t1" is the time interval between the final and initial velocities. The SI unit for acceleration is meters per second squared (m/s2), while the British imperial unit is feet per second squared (ft/s2).Full Answer >
