RESULTANT FORCES

Question 1

What is a resultant force?

Answer 1

A resultant force is the overall force that acts on an object.

Question 2

How do you calculate the resultant force?

Answer 2

You calculate the resultant force by considering the direction it is acting in.

Question 3

What is the resultant force when forces are acting in the same direction?

Answer 3

Resultant force = 20N + 10N = 30N

Example: Two forces of 20N and 10N acting together give a resultant force of 30N.

Question 4

What is the resultant force when forces are acting in opposite directions?

Answer 4

Resultant force = 20N - 10N = 10N to the left

Example: Two forces of 20N and 10N acting in opposite directions give a resultant force of 10N to the left.

Question 5

What is an example of a resultant force diagram?

Answer 5

A book resting on a table with a normal reaction force of 1N and weight of 1N.

Question 6

What is another example of a resultant force diagram?

Answer 6

Skiing down a hill with friction of 300N, normal reaction force of 300N, and weight of 500N.
