PQ 11.2 NEWTON’S THREE LAWS OF MOTION

What is the first law of motion also known as?

• Law of Gravity

• Law of Acceleration

• Law of Action-Reaction

• Law of Inertia

According to Newton's first law of motion, an object will remain in its state of motion unless acted upon by an external force. This tendency for an object's state of motion to remain unchanged is known as:

• Friction

• Gravity

• Inertia

• Acceleration

What is the formula for Newton's second law of motion?

• F = m/a

• F = mv

• F = m^2

• F = ma

The second part of the law of acceleration relates to the mass of the object being hit. According to this part, the acceleration of an object is inversely proportional to its:

• Mass

• Force

• Friction

• Velocity

Newton's third law of motion is also known as the law of:

• Acceleration

• Gravity

• Action-Reaction

• Inertia

When a basketball player jumps to make a slam dunk, the action of pushing against the court floor leads to a reaction force. What is the reaction force in this scenario?

• The ball pushing back

• The air resistance

• The player's weight

• The floor pushing back

In the context of an object at rest, what is the force exerted by the kettlebell on the floor?

• Magnetic force

• Acceleration force

• Frictional force

• Weight

What did Newton famously write to a colleague about his accomplishments?

• I have seen further by standing on the shoulders of giants

• I have invented calculus

• Let Newton be and all was light

• I have discovered the laws of motion

In curling, what is purposely enhanced to increase frictional force?

• The temperature of the ice sheet

• The smoothness of the ice sheet

• The pebbling of the ice sheet

• The thickness of the ice sheet

What did Alexander Pope capture about Newton's contributions to the world of science?

• Nature and nature's laws lay hid in night

• If I have seen further, it is by standing on the shoulders of giants

• The force of gravity is directly proportional to the mass of an object

• Let Newton be and all was light
