Exploring Newton's Laws of Motion

Who was Sir Isaac Newton and what fields did he contribute to?

• Geologist, historian, and artist

• Biologist, chemist, and sociologist

• Economist, musician, and philosopher

• Mathematician, astronomer, and physicist

What does Newton's First Law state about objects in motion?

• They will immediately stop when force is applied

• They will slow down over time unless additional force is applied

• They will stay in motion unless acted upon by an unbalanced force

• They will change direction unless acted upon by an unbalanced force

What must occur for an object at rest to move according to Newton's First Law?

• An unbalanced force must be applied

• It must be observed for a certain period

• It must interact with another object at rest

• It must be in a vacuum

What is inertia as described in Newton's First Law?

• The motion of an object in a circular path

• The tendency of an object to increase its speed

• The ability of an object to fly

• The resistance of any physical object to any change in its velocity

According to Newton's Second Law, what two factors determine the acceleration of an object?

• Mass and velocity

• Velocity and time

• Mass and force applied

• Force and mass

How can you increase the force on an object according to Newton's Second Law?

• Reduce both mass and acceleration

• Increase the velocity only

• Increase either the mass or the acceleration

• Decrease the mass and increase the acceleration

How does increasing the mass of a bowling ball affect its force according to Newton's Second Law?

• Increases the force

• Decreases the force

• Has no effect on the force

• Reduces the acceleration only

What does Newton's Third Law state about actions and reactions?

• Every action has no reaction

• Every action has an equal and opposite reaction

• Every reaction precedes an action

• Actions and reactions are always unequal
