At what point of the path of motion velocity will be perpendicular to the initial velocity?

A point mass is projected from origin with certain speed at a certain angle with horizontal. When the particle is at point (8m,6m), its velocity is perpendicular to direction of initial velocity.

Does initial velocity equal projectile motion velocity?

For ideal conditions, initial velocity equals final velocity if, but only if, initial and final elevations (Y) are equal. In fact during flight, the velocity on the way up at a given elevation (Yn) is the same as the velocity on the way down at that same elevation (Yn).

Does velocity stay the same in 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.

Which of the following is true about projectile motion?

TRUE – Absolutely true! Projectiles are objects being acted upon by gravity alone. As such, there is a vertical acceleration but no horizontal acceleration. The horizontal velocity of a projectile is either zero or a constant nonzero value.

At what point of a projectile motion acceleration and velocity of projectile are perpendicular to each other?

At the top most point.

At what time velocity of projectile is perpendicular to initial velocity?

Hence, we can say that when velocity is non-zero and velocity is not constant; a body moving with a constant magnitude of velocity(constant speed) with changing direction will have its acceleration perpendicular to its velocity.

What is the initial velocity in projectile motion?

(a) As mentioned earlier, the time for projectile motion is determined completely by the vertical motion. Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m above its starting altitude spends 3.79 s in the air.

How does the range of projectile depends upon its velocity?

The horizontal range of projectile is directly proportional to square of velocity by which the body is projected.

Which of the following statements is true regarding the horizontal velocity of projectile motion?

A projectile with a horizontal component of motion will have a constant horizontal velocity. The final horizontal velocity of a projectile is always equal to the initial horizontal velocity.

When velocity of an oblique is perpendicular to its acceleration?

At the highest point velocity is perpendicular to acceleration. Thus it is only once.

In which condition a body has an acceleration with zero velocity?

When the body is projected vertically up, at the highest point its speed becomes zero whereas it is accelerating downwards with g = 9.8 m/s2.

What is the horizontal velocity of a projectile?

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. In this portion of Lesson 2 you will

What is the angle of acceleration in projectile motion?

Projectile motion has 2 compounds horizontal & vertical μsinθ & μcosθ (4 is the initial velocity). Acceleration is only vertical in projectile motions. So there is always some angle between velocity of acceleration. But at the top most point of flight, only μcosθ (horizontal) in present but acceleration (g) in vertical, just st one instant.

What are the two key principles of projectile motion?

The numerical information in both the diagram and the table above further illustrate the two key principles of projectile motion – there is a horizontal velocity that is constant and a vertical velocity that changes by 9.8 m/s each second.

Why do projectiles travel with a parabolic trajectory?

Projectiles travel with a parabolic trajectory due to the influence of gravity, There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, 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,
