Show transcript
Pushes and pulls are forces. Different types of forces can be contact or non-contact forces.
Forces can change an object's speed, direction, and/or shape.
Forces can be measured using a force meter, also known as a newton meter.
A force meter works by stretching a spring – as the downward force due to gravity increases, the spring stretches.
Forces are measured in newtons (N), named after Sir Isaac Newton.
