Understanding Newton's Laws of Motion

Who published the three laws of motion in 1687?

• Albert Einstein

• Nikola Tesla

• Galileo Galilei

• Isaac Newton

What does Newton's first law of motion focus on?

• Gravity

• Acceleration

• Inertia

• Velocity

According to Newton's first law, what will an object at rest do unless acted upon by a force?

• Accelerate randomly

• Remain at rest

• Decrease in mass

• Move at constant velocity

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

• F = kx

• v = u + at

• s = ut + 1/2at^2

• F(net) = ma

What does 'ma' in the formula F(net) = ma stand for?

• Motion and acceleration

• Mass x area

• Mass x acceleration

• Maximum altitude

What is the value of acceleration due to gravity (small g) used in calculations?

• 10 m/s^2

• 9.81 m/s^2

• 9.8 km/s^2

• 5 m/s^2

What does Newton's third law state?

• For every action, there's an equal and opposite reaction

• Force equals mass times acceleration

• Velocity remains constant unless acted upon by a force

• Energy is neither created nor destroyed

What is the normal force an example of?

• A net force

• A frictional force

• A gravitational force

• An action-reaction force pair

What does the normal force do when more force is applied to it?

• It decreases

• It remains constant

• It increases

• It becomes zero

What is used to calculate the force of gravity on an object?

• F = kx

• F(g) = mg

• F(g) = ma

• F(net) = ma
