Consider a ball after it is thrown and going upward. The force on the ball is a). the force of gravity or b). some values between the force of gravity and the force of throw. What is the acceleration and what is the values of the acceleration. Explain your answer.
The acceleration is always g (downwards) and the force of gravity (called "weight") is M g. You should look up the value of g.
The "force of the throw" ceases when the ball is released.
To determine the acceleration of the ball after it is thrown upwards, we need to consider the forces acting upon it.
The two main forces at play are the force of gravity and the force of the throw.
At the moment the ball is released, the force of the throw no longer acts on the ball. This means that only the force of gravity is affecting the ball's motion. The force of gravity always acts downwards, towards the center of the Earth.
The acceleration of the ball is directly related to the force acting on it through Newton's second law, which states that force equals mass times acceleration (F = ma).
In this case, the force of gravity is equal to the weight of the ball, which can be calculated as the mass of the ball multiplied by the acceleration due to gravity (g). The value of g varies depending on the location on Earth, but it is approximately 9.8 m/s^2 near the Earth's surface.
Therefore, the acceleration of the ball while it is going upwards is equal to the acceleration due to gravity (g), and its value is always approximately 9.8 m/s^2 downwards. The other values between the force of gravity and the force of throw are not applicable once the ball is released, as the force of the throw is no longer present.
In summary, the acceleration of the ball is always equal to the acceleration due to gravity (g), and its value is approximately 9.8 m/s^2 downwards.
