When explaining a Newton, the kids must be told it is an SI Unit of measurement, from the International System of Units, which are an internationally recognized standard. After that, the concept of force has to be explai... More » Science Physics

Riding a bike is an example of Newton's third law of motion because the force needed to pedal a bike forward, which is the force that the tire exerts on the ground, is equal to the force of the ground pushing against the... More » Science Physics Motion & Mechanics

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 obj... More » Science Physics Motion & Mechanics
