Forces and their effects – basic principles
How it works
Forces are influences that can deform a body or change its state of motion. They are measured in Newton (N). Forces can pull or push and have direction, point of application and magnitude. Typical effects are acceleration, deceleration, change of direction or deformation. The weight force is a special force caused by gravity. Even if a body remains at rest, forces can act on it and balance each other out. Force arrows show the direction and magnitude of the force.
Note
A force can deform a body or change its state of motion. However, several forces can also balance each other out; then forces are acting, but the state of motion does not change. Forces are described by direction, point of application and magnitude.

An example
Which of the following processes shows the effect of a force?
If a ball becomes faster through a kick, a force is acting, because the state of motion changes. The correct answer is: The ball becomes faster.
