4.1 Work Done by a constant Force
... the work depends only on the component of force in the direction of motion and not the force perpendicular to the motion. Suppose, for example, you are shovelling snow. You might push on the snow at an angle θ to the ground, but the snow moves horizontally (Figure 1). The component of force directed ...

... A drag force is the force exerted by a fluid on the object moving through the fluid. This force is dependent on the motion of the object, the properties of the object, and the properties of the fluid (viscosity and temperature) that the object is moving through. As the ball’s velocity increases, so ...

... First Law: If the net force exerted on an object is zero the object continues in its original state of motion; if it was at rest, it remains at rest. If it was moving with a certain velocity, it will keep on moving with the same velocity. Second Law: The acceleration of an object is proportional to ...

... Magnitude of torque is defined as the product of the force exerted on the object to rotate it and the moment arm. When there are more than one force being exerted on certain points of the object, one can sum up the torque generated by each force vectorially. The convention for sign of the torque is ...
