Forces

Friction is the force that is created when two objects move across one another and it "acts to oppose the motion between" them (Prescott, p.90, 2013).

Prescott (p.90, 2013) states that "a force is a pushing or pulling action which can change the shape of an object, or make a stationary object move or a moving object change its speed or direction".

Air resistance is a force that only occurs when an object is moving in the air, and is a specific type of friction with the object and air being the two things that are moving against one another (Henderson, 2015).

A normal force is a force where objects are pushing against one another in stationary positions, one object's force is a support force as it holds the other object upright in place (Henderson, 2015).

​"Gravitational force (or gravitation or gravity) is the force of attraction that objects have on one another because of their masses" (Prescott, 2013).

​Magnetic force occurs between moving electrically charged particles that are either attracted to one another or repel one another (Encyclopedia Britannica, Inc.,. 2014).

"The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it" (Henderson, 2015).

Tension force occurs on a string, cable, rope, etc. that is connected to two objects and pulled tight because of the force between the two objects (Virtual Ink Ltd., 2007).

Applied force is when a force is applied to an object, such as a push and a pull.

"The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it" (Henderson, 2015). ​
