types of forces in physics textbook year 7

types of forces in integrated science syllabus.

2. Forces
Some examples of forces are...
Forces are measured in newtons, using a
newton meter.
The unit of force is named after Isaac Newton, who first theorised about
forces.

3. Contact Forces
Friction, air resistance, water resistance and buoyancy (upthrust) are
all examples of contact forces.
A contact force occurs when the objects are touching.

8. Non-Contact Forces
Gravity, magnetism and electrical forces, such as electrostatic, are
examples of non-contact forces.
A non-contact force occurs when the objects are not touching.
