Forces and Motion Quiz

Match the following forces with their effects on objects:

• The force that powers a light bulb.

• Gravity

• The force that pulls a thrown ball back to the ground.

• Electricity

• The force that attracts iron objects.

• Friction

• The force that resists the motion of a sliding object.

• Magnetism

Answer explanation

The force that pulls the ball back toward the ground when it is thrown up is called gravity. Gravity is the natural phenomenon that attracts objects with mass toward each other, specifically towards the center of the Earth.

While playing soccer, Olivia noticed that the ball eventually stops rolling on the grass. (a)   is a contact force that causes the ball to stop.

• Friction
• Gravity
• Magnetism
• Electricity

Answer explanation

Friction is a contact force because it occurs when two surfaces interact directly. In contrast, gravity, magnetism, and electricity are non-contact forces that act at a distance without physical contact.

Aubrianna is observing a car moving on a straight road. She notes down the distance covered by the car at different times. What does a distance-time graph show?

• The relationship between distance and time

• The relationship between force and mass

• The relationship between speed and direction

• The relationship between gravity and weight

Answer explanation

A distance-time graph illustrates how distance changes over time, showing the relationship between these two variables. This helps in understanding the speed and movement of the car, making the first choice the correct answer.

Raghad and Olivia are playing with magnets. Which of the following is an example of a force acting at a distance?

• Pushing a box

• Pulling a rope

• Magnetic attraction

• Kicking a ball

Answer explanation

Magnetic attraction is a force that acts at a distance without direct contact, unlike pushing a box, pulling a rope, or kicking a ball, which require physical interaction.

Match the scenarios with the outcomes when an unbalanced force is applied.

• A magician performing a vanishing trick

• It becomes lighter

• A helium balloon rising in the air

• It disappears

• A book lying on a table without being pushed

• It stays at rest

• A car accelerating on the highway

• Its speed or direction changes

Answer explanation

When Ava applies an unbalanced force to the cart, it will accelerate, causing its speed or direction to change. This is in accordance with Newton's second law of motion.

During a science class, Neviah and Colt were discussing why scientific knowledge is considered durable. Which of the following best describes their conclusion?

• It never changes

• It is open to change with new evidence

• It is based on opinions

• It is always correct

Answer explanation

Scientific knowledge is durable because it is open to change with new evidence. This adaptability allows science to refine and improve its understanding of the world, rather than being static or based solely on opinions.

Olivia and Colt are comparing two objects. If the objects have more mass, what happens to the gravitational force between them?

• It decreases

• It increases

• It stays the same

• It disappears

Answer explanation

According to Newton's law of universal gravitation, the gravitational force between two objects increases as their mass increases. Therefore, if Oliver and Ava compare objects with more mass, the gravitational force between them increases.

Aubrianna and Colt are discussing different types of forces they learned in science class. Which of the following is NOT a type of force?

• Gravity

• Magnetism

• Friction

• Temperature

Answer explanation

Temperature is a measure of thermal energy, not a force. In contrast, gravity, magnetism, and friction are all types of forces that act on objects.

Olivia is riding her bicycle on a straight road. What does the slope of the distance-time graph of her journey represent?

• Force

• Speed

• Mass

• Direction

Answer explanation

The slope of the distance-time graph represents speed, as it shows how distance changes over time. A steeper slope indicates a higher speed, while a flatter slope indicates a lower speed.

Raghad and Madison are curious about the force that keeps the planets in orbit around the Sun. The force responsible for this is (a)  

• Friction
• Gravity
• Magnetism
• Electricity

Answer explanation

The force that keeps the planets in orbit around the Sun is gravity. It is the attractive force between the Sun and the planets, ensuring they follow curved paths rather than flying off into space.
