Drag Forces and Air Resistance

Question 1

define a drag force

Answer 1

The forces acting in the opposite direction to the object’s motion

Question 2

True or false Drag forces increase with increased speed

Answer 2

True

Question 3

what is a fluid?

Answer 3

Liquid or gas

Question 4

what does air resistance depend on?

Answer 4

Speed

Question 5

what is terminal velocity?

Answer 5

when the acceleration of an object is 0 because the drag force or air resistance is equal to the force of acceleration.

Question 6

What is a gravitational field crated by?

Answer 6

any object with a mass

Question 7

what will happen if you put an object with mass in the gravitational field of another object

Answer 7

they will attract each other

Question 8

what is the equation for gravitational field strength?

Answer 8

gravitational field strength = Force / mass

Question 9

what is a gravitational field?

Answer 9

the force experianced per kg of mass

Question 10

what is the gravitational field strength on earth?

Answer 10

9.81 N/kg

Question 11

what does the graph of terminal velocity on a V T graph look like?

Answer 11

increases but has a decreasing gradient when it reaches terminal velocity there is no more gradient it is only a constant line because it would be traveling at a constant velocity
