The volleyball may accelerate more quickly or slowly depending on its mass.
The volleyball may accelerate more quickly or slowly depending on its mass.
The volleyball accelerates more quickly toward the ground when released from a higher height.
The volleyball accelerates more quickly toward the ground when released from a higher height.
The volleyball accelerates more slowly toward the ground when released from a higher height.
The volleyball accelerates more slowly toward the ground when released from a higher height.
The volleyball accelerates the same amount toward the ground each time.**
2. A student is setting up an experiment with 10 different balls. The student wants to measure which ball hits the ground with the largest force when released from a box 5 feet above the ground. Which quantity should be measured to correctly calculate the force with which each ball hits the ground?
the rate at which the velocity of each ball increases
the final velocity of each ball right before hitting the ground
the mass of each ball**
the initial velocity of each ball
3. Two balls are released from the same height on the moon. They both reach the ground at the same time. Which statement is correct about the two balls?
The balls have the same weight.
The balls have the same mass.
The balls have the same momentum.
The balls have the same acceleration. **
4. Two balls are released from the same height. Ball A is released on the surface of Earth, and ball B is released on the surface of the moon. The mass and net force on each ball are recorded in the table.
Net Force (N) Mass (kg)
Ball A 19.6 2
Ball B 9.6 6
Ball C 6.6 ?
Which statement is correct about the mass of ball C, which is released on the surface of the moon from the same height?
The mass of ball C is greater than the mass of ball A but less than the mass of ball B.**
The mass of ball C is greater than the masses of ball A and ball B.
The mass of ball C is less than the masses of ball A and ball B.
The mass of ball C cannot be determined from the information provided.
