Newton's Laws of Motion Quiz

What event is famously associated with Isaac Newton's discovery of gravity?

• An apple falling on his head

• A lightning strike

• A falling star

• A rolling stone

What happens to an object at rest according to the First Law of Motion?

• It will start moving on its own

• It will stay at rest until an unbalanced force acts on it

• It will accelerate

• It will change direction

What can an unbalanced force cause according to the Laws of Motion?

• An object to change color

• An object to start moving or stop

• An object to shrink

• An object to become invisible

What does Newton's Second Law of Motion state?

• An object's acceleration depends on its mass and the force acting on it.

• An object's speed is constant regardless of force.

• An object's mass is irrelevant to its acceleration.

• An object's velocity is always increasing.

What is the formula used in Newton's Second Law of Motion?

• Force = Mass x Acceleration

• Force = Mass + Acceleration

• Force = Mass / Acceleration

• Force = Mass - Acceleration

What does the term "accelerate" mean?

• A change in velocity or direction

• A constant speed

• A decrease in mass

• A fixed direction

What is the definition of "velocity"?

• Speed in a given direction

• Speed without direction

• Mass in motion

• Force applied over time

What happens to an object when an unbalanced force acts upon it?

• It remains at rest.

• It changes its speed and sometimes direction.

• It always moves in a circle.

• It disappears.

What is velocity?

• Speed in a given direction.

• The weight of an object.

• The color of an object.

• The size of an object.

What happens when an unbalanced force acts in the opposite direction of an object's motion?

• The object speeds up.

• The object slows down or decelerates.

• The object changes color.

• The object becomes larger.
