If a tennis ball hits a racket with Possible Answers:
Correct answer: Explanation: Newton's third law states that every force has an equal and opposite force. That means that Remember, this force will be negative as it is equal and OPPOSITE. That means it is moving in the opposite direction.
A bat hits a baseball with Possible Answers:
Correct answer: Explanation: Newton's third law states that when object A exerts a force on object B, object B exerts a force equal in magnitude but opposite in direction on object A. That means that if the force of the bat on the ball is
A hammer strikes a nail with Possible Answers:
Correct answer: Explanation: Newton's third law states that for every force, there is an equal and opposite force. The force of the hammer on the nail will be equal in magnitude, but opposite in direction, to the force of the nail on the hammer. Mathematically, that would mean The nail would exert
Two skaters push off of each other in the middle of an ice rink. If one skater has a mass of Possible Answers:
Correct answer: Explanation: For this problem, we'll use Newton's third law, which states that for every force there will be another force equal in magnitude, but opposite in direction. This means that the force of the first skater on the second will be equal in magnitude, but opposite in direction: Use Newton's second law to expand this equation. We are given the acceleration of each skater and the mass of the first. Using these values, we can solve for the mass of the second. Notice that the acceleration of the second skater is negative. Since she is moving in the opposite direction of the first skater, one acceleration will be positive while the other will be negative as acceleration is a vector. From here, we need to isolate the mass of the second skater.

A rock strikes a window with Possible Answers:
We need to know how long the two were in contact to solve
We need to know the mass of the rock to solve
Correct answer: Explanation: Newton's third law states that when one body exerts a force on another body, the second body exerts a force equal in magnitude, but opposite in direction, on the first body. Mathematically, this process can be written as: Since the rock exerts
A boy falls out of a tree and hits the ground with Possible Answers:
We must know the mass of the boy to solve
Correct answer: Explanation: Newton's third law states that when one object exerts a force on another object, that second object exerts a force of equal magnitude, but opposite in direction on the first. That means that: Using the value from the question, we can find the force of the ground on the boy.
A hunter fires a rifle. The rifle kicks back with Possible Answers:
We don't have enough information to solve.
Correct answer: Explanation: If the rifle exerts a force of This is because of Newton's third law, which states that when one object exerts a force upon another object, the second object exerts a force equal in magnitude but opposite in direction to the first force. Mathematically that means
Which of Newton's laws explains why it is easy for you to lift a 1L jug of milk from the fridge, but impossible to lift a 1000L jug? Possible Answers:
Correct answer: More than one of these Explanation: The answer is more than one. The two laws that come into play are Newton's first and second laws. Newton's first law is best known as the law of inertia. It states that an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force. Newton's second law relates the acceleration of an object to the mass and the forces acting on it with the equation
Two skaters push off of each other in the middle of an ice rink. If one skater has a mass of and an acceleration of , what is the mass of the other skater if her acceleration is ? Possible Answers:
Correct answer: Explanation: For this problem, we'll use Newton's third law, which states that for every force there will be another force equal in magnitude, but opposite in direction. This means that the force of the first skater on the second will be equal in magnitude, but opposite in direction: Use Newton's second law to expand this equation. We are given the acceleration of each skater and the mass of the first. Using these values, we can solve for the mass of the second. Notice that the acceleration of the second skater is negative. Since she is moving in the opposite direction of the first skater, one acceleration will be positive while the other will be negative as acceleration is a vector. From here, we need to isolate the mass of the second skater.
