1.) The equal and opposite forces described by Newton's third law of motion will balance each other out in many cases.

True False 2.)A biker is making a turn around the corner. The biker's speed remained constant at 12 miles per hour during the entire turn. Which of the following statements describes the forces on the biker?

A: The forces were balanced to keep the biker with a constant speed. b: The forces were unbalanced as the biker made the turn. c: The forces were balanced due to the biker's inertia. d: The forces were unbalanced due to the action-reaction pair required to turn. 3.) Which of the following will a scientific law do?

A: It will attempt to explain why something happens. B: It will describe a relationship that exists in nature. C: It will generate debate after it has been discovered. D: It will replace a theory when a hypothesis is rejected. 4.) Theories will usually turn into laws after scientists come up with a detailed formula that shows the relationship between events.

True False 5.) A player kicks a soccer ball down the field. It rolls to a stop just before the goal. Which statement accurately describes the motion of the soccer ball?

A: Inertia moves the ball until it runs out of force. B: The ball loses inertia due to an unbalanced force. C: A balanced force keeps the ball in motion until it stops. D: An unbalanced force causes the ball to stop. 6.) Consider the scenario of a small car hitting a large truck at rest from the side. Which statement is true?

A: The car exerts a greater force on the truck than the truck does on the car. B: The truck exerts a greater force on the car than the car does on the truck. C: The car exerts a force on the truck, and the truck exerts no force on the car. D: The car and the truck exert equal forces on each other. 7.) What would be the reaction force for the following action force: Right fist hits punching bag.

A: Left fist hits punching bag. B: Right fist gets bruised. C: Punching bag moves backwards. D: Punching bag hits right fist. 8.) Assuming all objects are moving with the same velocity, which statement describes the object with the smallest inertia?

A: A bowling ball rolls across a street and into a large soccer field. B: A driver continues forward after his car takes a sharp turn. C: A helicopter is following a high-speed pursuit across town. D: A pebble is thrown in space and continues in a straight line. 9.)

a. Create and describe a scenario in which the forces acting on an object are unbalanced. Explain how you know the forces are unbalanced. b. For your scenario, explain how Newton's third law of motion describes the forces involved
