Which quantity is zero at maximum height?

Which quantity is zero at maximum height?

Maximum Height, H: The maximum height of a object in a projectile trajectory occurs when the vertical component of velocity, vy , equals zero.

What quantities are zero for a projectile during its entire flight?

When a projectile reaches maximum height, the vertical component of its velocity is momentarily zero (vy = 0 m/s). However, the horizontal component of its velocity is not zero.

At which part of its trajectory does a projectile have zero velocity?

At the peak itself, the vertical velocity is 0 m/s; the velocity vector is entirely horizontal at this point in the trajectory. These concepts are further illustrated by the diagram below for a non-horizontally launched projectile that lands at the same height as which it is launched.

When a projectile is at the height highest point of its trajectory the direction of its velocity and acceleration are?

Direction of velocity is always tangent to the path so at the top of trajectory, it is in horizontal direction and acceleration due to gravity is always in vertically downward direction.

Why is velocity zero at maximum height?

The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.

Which of the following is largest when the height attained by the projectile is the largest?

So, Time of flight will be maximum.

Which of the following quantities remain constant all throughout the flight of a projectile?

average acceleration
The given quantity is average acceleration, which should remain constant as acceleration is constant.

What is the path followed by a projectile?

The path followed by a projectile is called a trajectory.

What is velocity at the highest point?

zero
At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.

When the projectile is at the highest point of its trajectory the direction of its velocity and acceleration are?

Direction of velocity is always tangent to the path so at the top of trajectory, it is in horizontal direction and acceleration due to gravity is always in vertically downward direction. It means angle between →v and →g are perpendicular to each other.

When a projectile is at the highest point of its trajectory?

When a projectile is at the highest point of its trajectory? when a projectile is at its highest point, the direction of its velocity and acceleration are perpendicular to each other. How do you find the velocity at the highest point in trajectory? The highest point in any trajectory, called the apex, is reached when vy = 0.

What is the vertical component of velocity at the highest point?

At the highest point of the trajectory the vertical component of velocity is zero. However, if the projectile hits its target before the vertical component of its velocity is reduced to zero, then at the highest point of the trajectory the distance of the projectile from its target is zero.

How do you solve problems in projectile motion?

Identify and explain the properties of a projectile, such as acceleration due to gravity, range, maximum height, and trajectory. Determine the location and velocity of a projectile at different points in its trajectory. Apply the principle of independence of motion to solve projectile motion problems.

What is kinematics in two dimensional projectile motion?

This fact was discussed in Chapter 3.1 Kinematics in Two Dimensions: An Introduction, where vertical and horizontal motions were seen to be independent. The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical.
