Physics of Buoyancy and Forces

What happens to the spring scale reading when the golf ball is submerged in water?

• It fluctuates randomly.

• It remains unchanged.

• It decreases to around 5 grams.

• It increases significantly.

Which force acts downward on the golf ball when it is submerged in water?

• Buoyant force

• Magnetic force

• Spring force

• Gravitational force

How is the buoyant force on the golf ball calculated?

• By using the density of water and the volume of the golf ball

• By using the surface area of the golf ball

• By multiplying the mass of the golf ball by gravity

• By measuring the change in spring scale reading

What is the force by gravity on the 50 gram golf ball?

• 0.437 newtons

• 0.600 newtons

• 0.490 newtons

• 0.053 newtons

Why does the spring scale not show the full weight of the golf ball?

• Because the water is too dense

• Because the golf ball is not fully submerged

• Because the buoyant force partially supports the ball

• Because the spring scale is faulty

What is the role of the buoyant force in this experiment?

• It increases the weight of the golf ball.

• It decreases the weight of the golf ball.

• It supports the golf ball partially.

• It has no effect on the golf ball.

What is the reading on the spring scale when the golf ball is submerged?

• 0.053 newtons

• 0.490 newtons

• 0.600 newtons

• 0.437 newtons

What principle explains the increase in digital scale reading when the golf ball is submerged?

• Archimedes' principle

• Newton's third law

• Newton's second law

• Newton's first law

What analogy is used to explain the increase in digital scale reading?

• Removing the golf ball from the water

• Tilting the beaker to one side

• Pouring more water into the beaker

• Adding a book on top of another book

What happens to the digital scale reading when the golf ball is submerged?

• It increases by the buoyant force.

• It remains the same.

• It decreases.

• It fluctuates.
