... A glass of water placed on a table remains there unless a force is applied to remove it. Similarly, if a car is moving with uniform velocity, it goes on moving with the uniform velocity. Objects will remain in their state of rest or motion unless a force acts to change the motion. Any change in moti ...

... The Sign of a Torque • Torque is a vector quantity. In this textbook, we will assign each torque a positive or negative sign, depending on the direction the force tends to rotate an object. • We will use the convention that the sign of the torque is positive if the rotation is counterclockwise and n ...

Skiing and External Forces
... Note that the steeper the slope the larger G1 will become, therefore the skier will accelerate more rapidly. As a ski is tipped up on edge it penetrates the snow and the snow presses back on the ski causing it to bend. The force from the snow pushing on the ski causes the skier to change direction. ...
