Speed and Newton's Laws Quiz

What is the formula to calculate speed?

• Speed = Distance * Time

• Speed = Distance - Time

• Speed = Distance / Time

• Speed = Time / Distance

According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by what?

• gravity

• an internal force

• an external force

• friction

What is the formula to calculate speed when given distance and time?

• speed = distance + time

• speed = distance * time

• speed = distance / time

• speed = distance - time

According to Newton's second law of motion, what is the relationship between force, mass, and acceleration?

• Force is directly proportional to acceleration but inversely proportional to mass

• Force is directly proportional to mass and acceleration

• Force is directly proportional to mass but inversely proportional to acceleration

• Force is inversely proportional to mass and acceleration

If an object is not moving, what is its speed?

• 0

• Undefined

• Negative

• 10

According to Newton's third law of motion, for every action, there is an equal and opposite what?

• inaction

• unequal reaction

• random reaction

• reaction

If a car travels 100 miles in 2 hours, what is its speed?

• 25 miles per hour

• 75 miles per hour

• 50 miles per hour

• 10 miles per hour

What is the unit of measurement for force?

• newton

• joule

• kilogram

• meter

If the force acting on an object is doubled, what happens to its acceleration?

• Acceleration will stay the same

• Acceleration will be halved

• Acceleration will become zero

• Acceleration will double

If the mass of an object is tripled, what happens to its acceleration if the force remains constant?

• The acceleration will be one-third of its original value.

• The acceleration will be doubled.

• The acceleration will be halved.

• The acceleration will remain the same.
