What is the unit for force?

• Joules (J)

• seconds (s)

• Newtons (N)

• meters (m)

How will this object move?

• The object will move to the left, as the forces are balanced.

• The object will move to the right, as the forces are unbalanced.

• The object will move to the left, as the forces are unbalanced.

• The object will move to the right, as the forces are balanced.
