is the acceleration of a bullet?

With its 127 mm barrel length, the bullet's acceleration is calculated to be 4.4 × 105 m/s2. The acceleration of a bullet depends largely on the gun from which it is fired, along with the intent of the user. Pistol bullets generally feature a lower acceleration than rifles or machine guns.

Acceleration is the rate of change of an object's velocity. Acceleration is a vector quantity, requiring both a magnitude and a direction. ... Velocity changes if the direction of travel or speed changes. Even if the object is moving at a constant speed, the object can be accelerating if the direction of travel changes.

The rate of change in speed/velocity is measured in metres per second squared. Acceleration is equal to the change of velocity divided by the time taken. Written as a and measured in m/s/s.

When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That's equivalent to over 1,800 miles per hour. To put that in perspective, it's amazing to realize that bullets travel over twice the speed of sound!

Then, explain your reasoning. At a projectile's highest point, its velocity is zero. At a projectile's highest point, its acceleration is zero.

The word acceleration implies a change in the object's velocity. One example of this is vertical particle projection. When an object is thrown upwards, the maximum height velocity of the body is zero, but constant acceleration due to gravity is still working.

The acceleration of a body is defined as the rate of change of its velocity. ... If its velocity is constant, the velocity is not changing at all, so the acceleration is zero.

The definition of acceleration. Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr.

Velocity is the displacement by an object per unit time. Acceleration is the change in velocity per unit time. So, a body in constant speed is said to have zero acceleration.

Acceleration is the time rate of change of velocity, so that can be found from the slope of a tangent to the curve on a velocity-time graph. ... During each interval, the acceleration is constant as the straight line segments show.

Here, accelerations deals with the rate of change in velocity, which means you need the change in velocity . In case, if the question means that if the velocity is always 0 then, the acceleration is always zero. But if the final velocity is zero then the acceleration is negative i.e deceleration. That's it.

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

Explanation: Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt.

Acceleration is simply a rate of change of velocity. So the magnitude tells you, how quickly velocity changes.

In space, the only force that would act to slow down (or speed up) that bullet after being fired is gravity. ... Anything moving through the air will encounter this force, so any bullets fired on the Earth will have their forward motions continuously slowed down by drag.

Then, explain your reasoning. At a projectile's highest point, its velocity is zero. At a projectile's highest point, its acceleration is zero. The rate of change of the \begin{align*}x\end{align*} position is changing with time along the projectile path.
