PS3 Lessons 3 &4 Forces and Motion

What is the net force for the following scenario. 100 N going left and 25 N going right.

• 125N

• 75N

• 75N left unbalanced

• 75N left balanced

When an object has no motion or is stationary it is.......

Calculate the net force for the diagram.

• 800 N down unbalanced

• 600N down balanced

• 400 N down unbalanced

• 400 N up unbalanced

Calculate the net force for the diagram.

When two force act in the same direction, how would you calculate the net force?

• Subtract the forces

• Balance the forces

• Add the forces

• Divide the forces.

What do you call a simple model to understand what will happen to an object due to the forces acting on it?

• Free Body Diagram

• Net Force

• Balanced Force

• Unbalanced Force

What is the Net force in this diagram?

• The forces action on the object.

• The combination of forces acting on the object.

• The size of the arrows.

• The size of the circle.

When forces are going in the opposite direction, how do you calculate net force?

• Add the forces

• Divide the forces

• Find a fraction of the forces.

• Subtract the forces.

It is defined as forces that are equal in magnitude.

• Unbalanced Forces

• Forces

• Balanced Forces

• Net force

It is defined as forces that are not equal in magnitude.

• Unbalanced Forces

• Forces

• Balanced Forces

• Friction
