Laws of Motion

Multiple Choice

Which of the following statements best describes Newton's First Law of Motion?

• An object in motion tends to stay in motion unless acted upon by an unbalanced force.

• Force equals mass times acceleration.

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

• Objects with more mass have less inertia.

Multiple Select

Select all statements that are true about inertia.

• Inertia is an object's resistance to a change in its motion.

• Inertia is caused because objects have mass.

• The less mass an object has, the more inertia it has.

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

Multiple Choice

What is the law of inertia also known as?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Gravity

Fill in the Blank

The formula for Newton's Second Law is F = ___ × a.

Multiple Choice

According to Newton's Second Law, what is the relationship between force, mass, and acceleration?

• Force equals mass times acceleration

• Force equals mass divided by acceleration

• Force equals acceleration divided by mass

• Force equals mass plus acceleration

Multiple Choice

If you increase the mass of an object but apply the same force, what happens to its acceleration?

• The acceleration decreases

• The acceleration increases

• The acceleration stays the same

• The acceleration becomes zero

Multiple Select

Which of the following statements are correct based on Newton's Second Law?

• More force results in more acceleration

• More mass requires more force to achieve the same acceleration

• Less mass requires less force to achieve the same acceleration

• More mass results in more acceleration
