Laws of Motion Quiz

What is Newton's First Law also known as?

• Law of Gravity

• Law of Acceleration

• Law of Inertia

• Law of Conservation of Energy

According to Newton's First Law, what happens to an object at rest when no external force is applied to it?

• It starts moving

• It remains at rest

• It disappears

• It changes color

Give an example of Newton's First Law in everyday life.

• A ball rolling uphill without any force applied to it.

• A book sliding across a table and eventually coming to a stop.

• A car continuing to move forward even after the driver takes their foot off the gas pedal.

• A person standing still on a moving train without falling over.

What is the formula for Newton's Second Law?

• F = ma

• a = F/m

• F = 1/2mv^2

• E = mc^2

According to Newton's Second Law, what happens to the acceleration of an object when the force acting on it increases?

• Acceleration increases

• Acceleration decreases

• Acceleration becomes negative

• Acceleration remains the same

Explain how Newton's Second Law applies to riding a bicycle.

• The force applied to the handlebars causes the bicycle to turn left.

• The force applied to the seat causes the bicycle to stop moving.

• The force applied to the pedals causes the bicycle to accelerate forward.

• The force applied to the pedals causes the bicycle to decelerate backward.

What is Newton's Third Law of Motion?

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

• The velocity of an object will remain constant unless acted upon by an external force

• The force of an object is equal to its mass times acceleration

• An object at rest will stay at rest unless acted upon by an external force

Provide an example of Newton's Third Law in action.

• When you sleep, your body pushes against the bed and the bed pushes back on your body with an equal force in the opposite direction.

• When you eat, the food pushes against your teeth and your teeth push back on the food with an equal force in the opposite direction.

• When you sit still, the chair pushes against you and you push back on the chair with an equal force in the opposite direction.

• When you walk, your foot pushes against the ground and the ground pushes back on your foot with an equal force in the opposite direction.

How does force play a role in real life situations?

• By causing objects to move, change direction, or stop.

• By creating new objects

• By causing objects to speak

• By making objects invisible

Explain how force is involved in the motion of a car.

• The car moves because of the force of the road pushing it forward.

• The engine's combustion of fuel creates a force that propels the car forward.

• The car moves because of the force of wind resistance pushing it from behind.

• The car moves due to the force of gravity pulling it forward.
