Resultant Forces

Question 1

What is ‘Thrust’?

Answer 1

• A force produced by the engines to push an aeroplane forward.

Question 2

How is ‘Air Resistance’ created?

Answer 2

• As the plane flies, air molecules push against it, producing an opposite force called air resistance

Question 3

What type of force is Air Resistance?

Answer 3

• A type of drag

Question 4

Define ‘Air Resistance’

Answer 4

• The force opposing the motion of an object moving through the air, sometimes called drag

Question 5

What happens when there is more than one force?

Answer 5

• When more than one force acts on an object, the effort is the same as if they were combined into a single force - the resultant force

Question 6

Define ‘Resultant Force’

Answer 6

• The total force that results from two or more forces acting on a single object, It is found by adding together the forces, taking into account their directions

Question 7

How do we work out forces?

Answer 7

• If they act in the same direction, we add.

- Opposite direction = Subtract
