Movimento Vertical da Bola de Futebol

At the highest point of its trajectory, what is the velocity of the soccer ball that was launched vertically upwards?

• The velocity is at its maximum value.

• The velocity is zero.

• The velocity is negative.

• The velocity is equal to its initial value.

Why does the velocity of the soccer ball decrease as it rises after being launched vertically?

• Because the ball is gaining kinetic energy.

• Because gravity acts in the opposite direction to the motion.

• Because the ball is being pushed by the wind.

• Because the ball is losing mass.

What is the name given in physics to the energy associated with the velocity of an object?

• Kinetic energy

• Potential energy

• Thermal energy

• Chemical energy

During the upward motion of a thrown ball, what happens to its velocity as it approaches the top of its trajectory?

• It decreases and reaches zero at the top.

• It increases and reaches a maximum at the top.

• It remains constant.

• It becomes negative.

As the ball descends after reaching the top, what happens to its velocity when it returns to the reference level (the height from which it was launched)?

• It increases and equals the initial launch velocity.

• It decreases and becomes zero.

• It remains constant.

• It becomes negative and less than the initial velocity.

What happens to the kinetic energy of a ball as it rises after being thrown upwards?

• It increases

• It remains constant

• It decreases

• It disappears

As a ball falls back down after reaching its highest point, what happens to its potential energy?

• It increases

• It remains constant

• It decreases

• It is converted to sound energy

During the upward motion of a thrown ball, what happens to its potential energy?

• It decreases

• It remains the same

• It increases

• It is converted to thermal energy

What is the main scientific concept being discussed in the learning material?
