MRJH Net Forces - Balanced/Unbalanced Forces

Forces Review

MRJH 24 - 25

​Learning Target #1a
I can calculate the net force on an object in a horizontal diagram.

​If forces are going in the same direction, ADD!

​Learning Target #1b
I can calculate the net force on an object in a horizontal diagram.

A: 9N - 3N =
Net Force = 6N, Right

B: 9N
Net Force = 9N, Right

C: 9N - 3N
Net Force = 6N, Right

D: 3N
Net Force = 3N, Right

​If forces are going in the opposite direction, SUBTRACT!

Multiple Choice

What is the net force of the object?

• 600 N, Right

• 600 N, Left

• 300 N, Right

• O N, No direction

Multiple Choice

What is the net force of the object?

• 100 N, Right

• 60 N, Left

• 40 N, Right

• 160 N, Left

​Learning Target #2a
I can calculate the net force on an object in a vertical diagram.

​If forces are going in the same direction, ADD!

​Learning Target #2b
I can calculate the net force on an object in a vertical diagram.

​If forces are going in the opposite direction, SUBTRACT!

Multiple Choice

What is the net force of the object?

• 15 N, Upward

• 5 N, Upward

• 15 N, Downward

• 15 N

​Learning Target #3
I can determine if the forces are balanced or unbalanced in a horizontal diagram.

​If net force = 0N,
forces are balanced

​If net force does not = 0N,
forces are unbalanced

Multiple Choice

Are forces balanced or unbalanced?

• Balanced

• Unbalanced
