Balanced and unbalanced forces

Are these forces balanced or unbalanced?

• Balanced

• Unbalanced

What is a balanced force?

• Two forces equal in size and acting in opposite directions on an object

• Two forces equal in size and acting in the same direction on an object

• Two forces unequal in size and acting in the same direction on an object

• Two forces unequal in size and acting in opposite directions on an object

Balanced forces can be....

• An object that's stationary

• An object travelling at the same speed without changing directions

• Both of the above

• None of the above

An unbalanced force is

• Two forces equal in size acting on an object

• Two forces unequal in size acting on different objects

• Two forces unequal in size acting on an object

• Two forces equal in size acting on different objects

Balanced forces do/do not cause a change in motion. Unbalanced forces do/do not cause a change in motion.

• Do not; Do

• Do; Do not

Which of the following is not a balanced force?

• 
• 
• 
• 

When forces are in 'equilibrium' it means

• The net (overall) force is 0N

• The net (overall) force is greater than 0N

• The object is stationary (not moving)

• Two force diagrams are pointing in the same direction on an object

A 'resultant force' means

• The forces on two objects are unbalanced

• The net (overall) force is 0N.

• The net (overall) force is greater than 0N.

• The object must be stationary (not moving)

What is the resultant force and direction?

• 70N right

• 60N left

• 10N right

• 130N right

What is the resultant force and direction?

• 600N down, 500N right

• 600N down, 900N right

• 0N centre, -500N left

• 500N right
