Physics Quiz: Laws of Motion and Momentum

What is inertia?

• The product of the amount of force acting on an object and the time interval for which the force acts

• The rate at which velocity changes with time

• The resistance an object has to a change in its state of motion

• The force that occurs when an object moves over another

According to Newton’s First Law of Motion, what happens to an object at rest?

• It accelerates in the same direction as the net force

• It stays at rest unless acted upon by an external unbalanced force

• It changes its state of motion

• It comes to a complete stop

What is the unit used for Force?

• Second

• Meter

• Newton

• Kilogram

What is the action-reaction force pair according to Newton’s Third Law of Motion?

• The force exerted on an object is the action, and the force experienced by the object is the reaction

• The force exerted on an object is the reaction, and the force experienced by the object is the action

• The force exerted on an object is the acceleration, and the force experienced by the object is the momentum

• The force exerted on an object is the momentum, and the force experienced by the object is the acceleration

What is impulse in terms of force and time interval?

• The resistance an object has to a change in its state of motion

• The rate at which velocity changes with time

• The distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop

• The product of the amount of force acting on an object and the time interval for which the force acts

Mass * Acceleration = ?

Are you confident about this test?

• YES! 😁

• Not Really 🙁

• No. I think I need to study more 📚

What is the relationship between force, mass, and acceleration according to Newton's Second Law of Motion?

• Force equals mass divided by acceleration

• Force equals mass times acceleration

• Force equals acceleration divided by mass

• Force equals acceleration times mass

What is the term for the force that opposes the motion of an object? (hint: opposite of applied force)

• Inertia

• Friction

• Gravity

• Momentum

What happens to the speed of an object when a balanced force acts on it?

• It increases

• It decreases

• It remains the same

• It becomes zero
