Is there any point at which acceleration is parallel to velocity?

The vertical component of velocity is the only one which is parallel to the acceleration due to gravity and as soon as it becomes zero, the only component which remains is horizontal.

What does it mean if acceleration is parallel to velocity?

acceleration tells you how fast the object’s velocity is changing. up; if is anti-parallel to the velocity, then the object is slowing down. If is parallel to the velocity, then the force speeds the object up; if is anti- parallel to the velocity, then the force slows the object down.

Is there any point on the trajectory of parabola at which velocity and acceleration are orthogonal?

Yes. Surprise: it is at the highest point of trajectory. Why? Since the highest point is the point where the vertical velocity is zero (it is the point where the vertical velocity component switches its sign), the projectile flies parallel to the ground at this instance of time.

Can acceleration and velocity vectors be parallel?

Velocity will be tangent to the arc, while the only acceleration is straight down (due to gravity) and never actually parallel to velocity, so long as there is a horizontal component to the trajectory.

Is there any point on the trajectory where V and A are parallel to each other if so where?

If v and a are parallel, the projectile has zero horizontal velocity. The horizontal velocity remains constant. Hence, we don’t have a point where the horizontal velocity is zero. It is impossible to v and a to be parallel for this projectile.

At what point of projectile path the speed is minimum?

highest point
At the highest point of the trajectory of a projectile, its speed is minimum. This is because the horizontal speed of the projectile remains constant. Now, the only force acting on the projectile is gravity, and the acceleration is that due to gravity, so its speed is minimum at the highest point of the trajectory.

Is there any point where V and A are parallel to each other?

Why does acceleration point towards the center of a circle?

Because velocity is a vector quantity (that is, it has both a magnitude, the speed, and a direction), when a body travels on a circular path, its direction constantly changes and thus its velocity changes, producing an acceleration. The acceleration is directed radially toward the centre of the circle.

At which point of projectile path acceleration is perpendicular to velocity?

When the particle is at point (8m,6m), its velocity is perpendicular to direction of initial velocity.

How the motion will change if direction of acceleration is parallel?

Answer: Yes, that’s right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down. That’s because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction.

How does the horizontal component of its velocity 1.0 s after launch compare with its horizontal component of velocity 2.0’s after launch?

In projectile motion, horizontal component of velocity remains constant as there is no acceleration in horizontal direction. And, horizontal component of velocity 1.0s after launch is equal to its horizontal component of velocity 2.0s after launch.

What quantities are constant during projectile motion?

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.

What is the acceleration vector of a parabola?

The acceleration vector is constant and parallel to the axis of the parabola, pointing away from the center. The axial component of the velocity vector is parallel to the acceleration vector on the side of the parabola where motion is away from the parabola’s center.

Is the velocity vector parallel to the path of an object?

The velocity vector varies in direction, but is never exactly downwards. so the answer is, no, it is never parallel. Perpendicular, yes, at the peak of the path, the velocity is pointing horizontally, with the acceleration pointing downwards.

Why is acceleration perpendicular to velocity at the highest point of path?

At the highest point of the path, the velocity of the projectile only has a horizontal component and here the acceleration is perpendicular to the velocity. The velocity is never parallel to the acceleration as for that to happen the horizontal component would have to be zero which is never the case.

What is the initial velocity of a particle in parabolic path?

Nowhere in the parabolic path, the velocity of a particle is vertically downwards or upwards, when it is projected at time t=0, with an initial velocity “u” at an angle other than 90° with the horizontal. At 90°, the particle moves vertically up and then falls vertically down.
