Contact and Non contact forces

Question 1

What are examples of a vector quantity

Answer 1

Force, Velocity, Displacement, Acceleration, Momentum

Question 2

What is a force

Answer 2

A push or pull on an object that is caused by it interacting with something
All forces are either contact or non contact

Question 3

What is a Scalar quantity

Answer 3

Physical quantities that only have magnitude and no direction

Question 4

What is a contact force

Answer 4

When two objects have to be touching for a force to act
e.g. friction, air resistance

Question 5

What is a non contact force

Answer 5

If the objects do not need to be touching for the force to act

Question 6

What is an interaction pair

act on two

Answer 6

A pair of forces that are equal and opposite and act on two interacting objects

Question 7

What is an example of scalar quantities

Answer 7

Speed, Distance, Mass, Temperature, Time

Question 8

What is a vector quantity

Answer 8

A quantity that has both magnitude and direction

Question 9

How can a vector quantity be drawn and what does it show

Answer 9

Drawn by arrow
The length of the arrow represents the magnitude the arrow points to the direction

Answer 10

Friction
Air resistance
Tension

Question 11

three examples of non contact forces

Answer 11

gravitational
Electrostatic
Magnetic
