what is the acceleration of a projectile in the horizontal direction?
318317
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.

This acceleration only changes the vertical velocity, so the horizontal velocity is constant. People can't remember what is zero at the maximum height. Vertical velocity is zero at this point, but there is still horizontal velocity and acceleration is still down.

There are two components of the velocity: one is horizontal, and one is vertical. The horizontal component of the velocity always has the same value all over the motion. Conclusion: ... Thus, the velocity and acceleration can never be parallel in the path of a projectile.

An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards.

At maximum height, the vertical component of the velocity is zero, leaving only the horizontal component. So the angle between velocity and acceleration is 90 degrees.

When an object is moving with a constant velocity, the line on the graph is horizontal. ... Acceleration can be calculated by dividing the change in velocity (measured in metres per second) by the time taken for the change (in seconds). The units of acceleration are m/s/s or m/s 2.

Answer and Explanation: An example of acceleration against the direction of motion is an object with no self-propelling capabilities moving straight up.

The trajectory has horizontal (x) and vertical (y) components. Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).

To find the time of flight, determine the time the projectile takes to reach maximum height. The time of flight is just double the maximum-height time. At maximum height, vy = 0. The time of flight is also determined solely by the initial velocity in the y direction and the acceleration due to gravity.

As such the projectile is accelerated and the speed of the ball in - y direction increases (acceleration). ... Deceleration results in decrease in speed i.e magnitude of velocity. In one dimensional motion, the “deceleration” is defined as the acceleration which is opposite to the velocity.

If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line). If the acceleration is negative, then the slope is negative (i.e., a downward sloping line).

For a projectile fired straight upwards , its velocity at max height = 0 whereas its acceleration at that instant is 'g' ( = 9.8 m/s² ) vertically downwards . So dot product of velocity and acceleration is zero at max hieght in this case .

A projectile that moves horizontally at 8km/s will follow a curve that matches the curvature of the Earth because the projectile has 29,000 kilograms per hour and 18,000 miles per hour. ... So that it stays in Earth's gravity, so it does not float into space.

When the object is moving in uniform circular motion, then the angle between the velocity vector and acceleration vector is equal to 90 degrees. In this case, the type of acceleration caused is generally called centripetal acceleration.

The height of release affects the trajectory of the projectile and, for a given speed of release and angle of release, the horizontal displacement increases as the height of release increases.

The maximum height of a projectile is half the range of the horizontal length.

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