Study Notes
Kraft
- A magnitude that describes how strong or weak a force is, and how it can cause an object to change its shape or velocity.
- A point where the force acts on an object, and is indicated by a thick dashed line.
- Measured using a tool such as a dynamometer.
Point of Application
- The exact location on an object where a force is applied.
- Represented by a thick, dashed line.
Dynamometer/Force Sensor
- A tool used to measure force.
Pull and Push Force
- Forces that cause objects to move or change shape.
- Forces that could cause objects to pull or push towards one another.
Magnetic Force
- A force resulting from a magnetic field.
Spring Force
- A force arising from tension in a spring.
Elastic Force
- A force acting on an object when it is stretched or compressed.
- An example would be a spring.
Gravity
- The force of attraction between any two objects with mass.
- The earth's pull on an object is called weight.
Normal Force
- The force that prevents objects from falling through surfaces.
Friction Force
- A resistant force between two surfaces in contact.
- The force that resists movement.
