________ is all about the interaction between objects.

force

15

Are forces that act between two objects that are physically touching each other.

contact forces

15

Two objects sliding past each other experience ___________ forces.

friction

15

An object moving through the air experiences ______ __________. For example, a skydiver falling through the air.

air resistance

15

______________forces are forces that act between two objects that are not physically touching each other.

non-contact

15

Examples of non-contact forces include:

Magnetic force, Electrostatic force, Gravitational force

15

Like charges

repel

15

opposite charges

attract

15

Calculate the gravity force (weight) of a skydiver with a mass 70 kg falling towards the Earth? (Remember that gravitational field strength = 10 N/kg on Earth).

700 N

15

The force that the Earth exerts on objects.

weight

15

It is important to remember that weight is not the same as mass. The weight of a person of the same mass is larger on earth due to the

earth's stronger gravity

15

If the force of gravity (weight) of a person on earth is 600 N, what will be his weight on the moon? Remember: The moon has 1/6 gravity of the earth.

100 N

15

The ____________ is an instrument that is used to measure force.

spring balance

15

The force of gravity (weight) ________________ as the mass increases. [increases or decreases]

increases

15

What happens to your mass on the moon? [increases, remains the same, decreases]

remains the same

15

The hair on our arms are attracted to the plastic wrap. What type of force is this?

electrostatic force
