Forces, Friction, and Gravity 2

If a car has a force of 54 N forwards and the brakes have a force of 73 N backwards, what is the overall Net Force.

• 16 backwards

• 19 backwards

• 19 forwards

• 23 forwards

How do you find the net force of this image.

• Add up all the arrows

• Add a green arrow and the orange arrow.

• Subtract all the arrows.

• Add the green arrows and subtract the orange arrow.

What is the net force and to what direction.

• 210 N to the right

• 280 N to the right

• 110 N to the left

• 180 N to the left

Is the Net Force balanced or Unbalanced?

• Balanced

• Unbalanced

With unbalanced forces, the object will move in the direction of the _______ force.

• equal

• smaller

• larger

You and your friend, are playing tug of war. Your friend pulls with a force of 55 N, to the rights. You pull with a force of 65 N, to the left. What is the net force on the rope?

• 20 N, to the left

• 20 N, to the right

• 10 N, to the right

• 10 N, to the left

If an object is moving, what does it have to be doing to still be considered a balanced force?

• moving at a constant speed

• be unbalanced

• stop moving

• slow down

an object with a zero net force could be moving

• True

• False

What is a force?

• the PUSH or PULL on an object 
• The MOTION an object creates
• The objects HITTING one another
• Going REALLY FAST

The diagram below shows a skateboarder pushing himself forward with a force of 25 N while the wind pushes back with a force of 5 N. How will the skateboarder be affected if the force of the wind increases to 8 N?

• The speed of the skateboarder will increase.
• The speed of the skateboarder will remain constant.
• The speed of the skateboarder will decrease.
• The skateboarder will come to a stop.
