Chapter 2 Lesson 4 Review

Newton’s 3^rd Law of motion states that any action will have a(n) ________and ______reaction

• Equal and similar

• Equal and opposite

• Equal and different

• Greater and opposite

What is Newton's third law of motion? Click all that apply.

• When one object exerts a force on a second object, the second object exerts a force of the same size but in the opposite direction.

• Newton's third law states that objects at rest stay at rest and objects in motion stay in motion.

• For every action, there is a greater reaction.

• For every action, there is an equal and opposite reaction.

Explain the concept of action and reaction in Newton's 3rd law.

• For every action, there is an equal and opposite reaction.

• The reaction always comes before the action

• Action and reaction are unrelated in Newton's third law

• For every action, there is a smaller reaction

How does Newton's third law impact the motion of objects?

• It only impacts the motion of large objects

• It has no impact on the motion of objects

• It impacts the motion of objects by causing them to exert equal and opposite forces on each other.

• It causes objects to move in the same direction

State the action and reaction forces when a person pushes a wall.

• The action force is the person pushing on the wall, and the reaction force is the wall pushing back on the person.

• The action force is the wall pushing on the person, and the reaction force is the person pushing back on the wall.

• The action force is the person pushing on the wall, and the reaction force is the wall pulling the person towards it.

• The action force is the person pulling on the wall, and the reaction force is the wall pushing back on the person.

How do force pairs relate to Newton's third law?

• Force pairs are unequal in magnitude and opposite in direction.

• Force pairs are equal in magnitude and random in direction.

• Force pairs are equal in magnitude and opposite in direction.

• Force pairs are equal in magnitude and same in direction.

Explain how Newton's third law affects the motion of a rocket during launch.

• The rocket experiences a force upwards, causing it to spin out of control.

• Newton's third law has no effect on the motion of a rocket.

• The rocket experiences a force in the same direction, slowing it down.

• The rocket experiences a force in the opposite direction, propelling it upward.

A book rests on a table. The force of GRAVITY pulls down on the book with a force of 20N. What PREVENTS the book from accelerating DOWNWARD at 9.8m/s²?

• The table and the book are pushing back with an acceleration of 9.8m/s².

• The inertia of the book is equal to the inertia of gravity.

• The table presses back up on the book with a force greater than 20N

• The table presses back up on the book with an equal and opposite force of 20N

You hit a wall with a stick. The EQUAL but OPPOSITE reaction is

• The wall pushing against you

• The stick pushing against you

• The wall pushing against the stick

• You pushing against the stick

Describe the other force in the action- reaction force pair.

• Pin exerts less force in the opposite direction as the ball

• Pin exerts less force in the same direction as the ball

• Pin exerts and equal but opposite force on the bowling ball

• The forces would be balanced
