What is the acceleration of a projectile when its instantaneous vertical velocity is zero at the top of its trajectory?
Acceleration at the point of zero vertical velocity will be equivalent to gravitational acceleration on that body. On Earth, for example, this is around 9.8 meters per second per second (9.8m/s2).
What is the vertical acceleration of a projectile if the vertical component of its velocity vector is zero?
The vertical component of a projectile's velocity is irrelevant. It can be up, down, or zero, makes no difference. As long as projectile motion lasts ... gravity is the only force on the object and you're ignoring air resistance ... its acceleration is constant, and is equal to the acceleration of gravity: 9.8 meters per second2 pointing down.
What is the speed of a projectile equal to at its highest point?
At the highest point of its trajectory, the speed of a projectile is equal to zero as it momentarily stops before starting to descend.
Why ax equals 0 for projectile motion?
In projectile motion, the horizontal acceleration (ax) is equal to 0 because there are no external horizontal forces acting on the object once it is launched. This means that the object continues to move at a constant horizontal velocity throughout its trajectory.
What is the acceleration of a projectile fired vertically down?
The acceleration of a projectile fired vertically down is equal to the acceleration due to gravity, which is -9.81 m/s^2. The negative sign indicates that the acceleration is in the downward direction.

The acceleration of a projectile fired vertically down is equal to the acceleration due to gravity, which is -9.81 m/s^2. The negative sign indicates that the acceleration is in the downward direction.
What is the acceleration on a projectile as it comes down?
The acceleration on a projectile as it comes down is approximately equal to the acceleration due to gravity, which is 9.81 m/s^2 on the surface of Earth. This acceleration acts in the downward direction and causes the projectile to increase in velocity as it falls towards the ground.
What is the acceleration of a ball at the top of its trajectory when thrown straight upward?
The acceleration of a ball at the top of its trajectory when thrown straight upward is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 downward. At the top of its trajectory, the ball momentarily comes to a stop before reversing direction and accelerating downward.
Is the vertical motion of a projectile accelerated?
Yes, the vertical motion of a projectile is accelerated due to the force of gravity acting on it, pulling it downward towards the Earth. This acceleration is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth.
What is the downward acceleration of a thrown object in projectile motion?
The downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
What is a freely falling projectile?
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
What is the acceleration of a stone at the top of its trajectory when it has been thrown straight upward?
At the top of its trajectory, the acceleration of the stone is equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 directed downward. This is because at the highest point, the stone momentarily comes to a stop before it starts falling back down.
What is the magnitude of the velocity of a vertical projectile at its maximum height is equal to?
The horizontal component of a projectile's velocity doesn't change, until the projectile hits somethingor falls to the ground.The vertical component of a projectile's velocity becomes [9.8 meters per second downward] greatereach second. At the maximum height of its trajectory, the projectile's velocity is zero. That's the pointwhere the velocity transitions from upward to downward.
