Newton`s Laws of Motion
... • Forces cause change in the motion, but so far we have only considered motion that changes the position of the object. • What about changing the “spin” or rotation of an object? • To get a nice introduction to the idea of torque, see the computer homework program on Basic Torque (Vol 1 #8).

Uniform Circular Motion
... Uniform circular motion can be described as the motion of an object in a circle at a constant speed. Remember what vectors represent…magnitude and direction. As an object moves around in a circle the magnitude of it’s velocity remains constant but the direction changes. This means it’s velocity is i ...

Mass and Weight
... The force of gravity on any object is actually the weight of the object! So this means that because weight is a force it is measured in NEWTONS! The thing we usually call ‘weight’ and is measured in kilograms and grams is really called the MASS! ...
