Question

When a ball is thrown straight up with no air resistance, the acceleration at its highest point. A) is upward B) is downward C) is zero D) reverses from upward to downward E) reverses from downward to upward

Answer 1

Answer:

B) is downward

Explanation:

The acceleration is always downward, because it is the gravitational acceleration.

When the ball is going up the acceleration is opposing the movement, and when the ball is going down the velocity has the same direction as the acceleration

Answer 2

When a ball is thrown straight up with no air resistance, the acceleration at its highest point is downward. Option B is correct.

What is acceleration?

The rate of change of the velocity is known as the acceleration. It is a time-based quantity having unit m/sec².

Because it is gravitational acceleration, the acceleration is always downward.

The acceleration opposes the movement when the ball is traveling up, and the velocity opposes the acceleration when the ball is heading down.

When a ball is thrown straight up with no air resistance, the acceleration at its highest point is downward.

Hence option B is correct.
