• Isaac Newton

• Galileo Galilei

• Nikola Tesla

Multiple Select

Which of the following are Newton’s Laws 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

• Energy cannot be created or destroyed

Multiple Choice

According to Newton's Laws of Motion, what happens to an object at rest if no unbalanced force acts upon it?

• It starts moving

• It remains at rest

• It accelerates

• It changes direction

Multiple Choice

According to Newton's First Law, what is required to change the motion of an object?

• A force

• Gravity

• Friction

• Energy

Multiple Choice

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

• An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

• An object at rest will always start moving on its own.

• An object in motion will eventually stop without any force.

• An object at rest can never move.

• Football on the field

• Basketball hoop

• All of the above

Multiple Choice

If the forces on an object are equal and opposite, what happens to the motion of the object?

• The object speeds up

• The object slows down

• The object experiences no change in motion

• The object moves in a circle

What is meant by unbalanced force?

Multiple Choice

Which of the following statements best describes unbalanced forces?

• Forces are equal and opposite, and the object does not move

• Forces are not equal and opposite, and the object's motion changes

• Forces are equal and in the same direction, and the object moves faster

• Forces are not equal and in the same direction, and the object stops

Multiple Choice

Which real-life example demonstrates the effect of an unbalanced force?

• A soccer ball sitting at rest until it is kicked

• A tug of war where both teams pull equally

• A book resting on a table

• A car parked on a hill with the brakes on

Multiple Choice

Which of the following best describes Newton's 1st Law of Motion?

• An object will remain at rest or in motion unless acted on by a force.

• An object will accelerate in the direction of the net force.

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

• Objects attract each other with a force proportional to their masses.

Why don't moving objects on Earth keep moving forever?

Multiple Choice

In outer space, away from gravity and friction, what would happen to a rocket ship launched with a certain speed and direction?

• It would eventually slow down and stop.

• It would keep going in the same direction and at the same speed forever.

• It would fall back to Earth.

• It would change direction randomly.
