According to Newton's first law, what will happen to an object at rest?

• It will start moving on its own.

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

• It will eventually fall due to gravity.

• It will move in a circular motion.

What is the relationship between force, mass, and acceleration as described by Newton's second law?

• Force = Mass + Acceleration

• Force = Mass × Acceleration

• Force = Acceleration / Mass

• Force = Mass - Acceleration

If a dodgeball is sitting on a table, which forces are acting on it?

• Only the force of gravity

• Balanced forces from the table and gravity

• Unbalanced forces causing it to roll off

• No forces acting on it

What happens to a dodgeball if the table is removed?

• It will float in the air.

• It will remain stationary.

• It will fall to the ground due to unbalanced forces.

• It will roll off the table.

How can we describe an object’s motion?

• By measuring its temperature

• By observing its speed and direction (velocity)

• By counting the number of forces acting on it

• By calculating its mass

What is acceleration?

• The speed of an object at rest

• A change in an object's velocity

• The distance traveled by an object

• The weight of an object

According to Newton's third law, what happens when a force is exerted on an object?

• The object will not move.

• The object will exert an equal and opposite force.

• The object will accelerate indefinitely.

• The object will stop moving.

If you throw a dodgeball harder, what will happen to its acceleration?

• It will decrease.

• It will remain the same.

• It will increase.

• It will stop.
