Study Guide

Jeopardy Procedures/ Rules 1. Work in the group you are assigned. 2. When question is displayed every group must write answer on their whiteboard. 3. The group that holds up their whiteboard first with the correct answer gets chosen. 4. One random person in that group will be called on to explain the answer- so make sure every knows why that is the answer. – If your group gets it right you get the points and get to pick the next question! 5. Most of the questions on this review are questions on your green review sheet- write correct answers as we go over them!

$200 $400 $600 $800 $1000 Types of Forces Balanced and Unbalanced Forces Newton’s Laws of Motion Gravity

Types of Forces $200 The combination of all forces acting on an object is called what?

$400 Types of Forces 8. What force describes how a skateboarder eventually comes to a stop?

Types of Forces $ Which end of a magnet is repelled by the south pole of a magnet?

Types of Forces $ What characteristics can you use to describe a force?

Types of Forces $ Complete the chart! Contact ForcesNon-Contact Forces

Balanced and Unbalanced Forces $200 What is the unit for measuring Force?

$400 Balanced and Unbalanced Force 19. State the following using the image 20N 5N Net Force: _______ Balanced or Unbalanced Force: _____ Object in Motion? Yes or No______

16. What is the difference between balanced and unbalanced force? $600 Balanced and Unbalanced Forces

$800 Balanced and unbalanced forces You exert a force of 30N on a chair & your friend comes to help and exerts a 25N force. What is the net force acting on The chair?

$1000 Balanced and unbalanced Forces 3. If a rope accelerates to the right during a game of tug a war, what is true about the force acting on the rope?

$200 Newton’s Laws of Motion 4. What is Newton’s 2 nd law of motion? What are the 3 variables?

$400 Newton’s Laws of Motion 5. If a force of 30N is applied to a 15kg rock what is the resulting acceleration?

$600 Identify the type of reaction… 7. Describe action-reaction forces? What is true about them?

$800 Newton’s Laws of Motion 13. According to Newton’s Third Law of Motion, what will happen to a boat if someone jumps forward off the boat?

$1000 Newton’s Laws of Motion 14. You and your friend smash into each other playing bumper cars and you both move backwards after you hit. This is an example of what law? Explain.

Gravity $200 What are 2 factors that effect gravity?

$400 Gravity As the force of gravity decrease does the distance from this force increase or decrease?

$600 Gravity 11. Why can a satellite move around the earth in a circular orbit at a constant height?

$800 Gravity 17. The ball in the diagram is thrown up into the air and follows the path shown. What causes the ball to follow the path beyond point B?

$1000 Gravity 6. Why is Earth’s gravity more than the Moon’s gravity?

$200 Types of Forces Net Force

$400 Types of Forces Friction- Resistance to Motion

$600 Types of Forces South Pole of the Magnet! Opposites attract, likes repel!

$800 Types of Forces Direction in which it acts Strength of the force

$1000 Types of Forces Contact ForcesNon-Contact Forces 1. Applied Force1. Gravitational Force 2. Normal Force2. Electrical Force 3. Friction3. Magnetic Force

$200 Balanced and Unbalanced Forces Newton (N)

$400 Balanced and Unbalanced Forces Net Force = 15N Unbalanced Force Object in Motion

$600 Balanced and Unbalanced Force Balanced forces have 2 forces that are equal but act in opposite directions and unbalanced forces change in motion, acceleration, and direction.

$800 Balanced and Unbalanced Forces Net Force = 55N ( )

$1000 Balanced and Unbalanced Forces The force on the right is greater than the force on the left. The forces are unbalanced.

$200 Newton’s Laws of Motion An objects acceleration depends on the mass and the force acting on it. Variables: mass, acceleration, force

$400 Newton’s Laws of Motion A = F/m 2m/s 2

$600 Identify the type of reaction… For every action there is a reaction for example a rocket launching. Action and Reaction forces are equal but act in opposite directions.

$800 Identify the type of reaction… The boat will move backwards or in the opposite direction. Action = reaction.

$1000 Identify the type of reaction… Bumper cars are in motion, an outside forces stops the motion (Newton’s 1 st law) The cars move backwards because of Newton’s 3 rd law of motion- action = reaction.

$200 Gravity Mass and Distance

$400 Gravity Distance increases

$600 Gravity Gravity and inertia (keeps it moving)

$800 Gravity

$1000 Gravity Earth has a greater mass then Mars and Mars has a great mass than the moon. Therefore, earth has more gravity then mars and Mars has more gravity than the moon. Remember Gravity has to do with distance and mass!

Good Luck on your test!
