Answer 12

Contact

Question 13

What are the 4 main types of contact force

Answer 13

• friction
• air resistance
• tension
• normal contact force

Question 14

What is the normal contact force also known as

Answer 14

Reaction force

Question 15

Scenario:

Rock on table

Describe the force

Answer 15

• The rock has a downwards force on the table which is its weight
• to stop the rock from moving the table has an upwards force that is equal and opposite

Question 16

What is meant by the normal contact force

Answer 16

When a contact has an equal and opposite force

Question 17

What are the 3 main types of non contact forces

Answer 17

• gravitational
• magnetic
• electrostatic

Question 18

When talking about non contact forces what can we refer them to

Answer 18

Field of influence around an object because forces can act on anything in that surrounding area

Question 19

True or False:
Gravity is a force between any two objects that have mass

Answer 19

True

Question 20

Are magnetic forces attractive or repulsive

Answer 20

Both depending on which end the poles lay
Opposite = attract
Same = repel
