What happens to a projectile if there is no air resistance?

Therefore, a projectile in motion will remain with the same horizontal velocity throughout its flight, since no force exists in the horizontal direction, but its velocity will change in the vertical direction due to the force of gravity. …

What are the assumptions made in the projectile motion?

Assumptions made in the study of projectile motion: (i) Acceleration due to gravity ‘g’ is constant both in magnitude and direction. (ii) There is no resistance due to air. (iii) The earth is flat.

What is the acceleration of a projectile vertically if there is no air resistance?

This is indeed consistent with the fact that there is a vertical force acting upon a projectile but no horizontal force. A vertical force causes a vertical acceleration – in this case, an acceleration of 9.8 m/s/s.

What is the horizontal acceleration of a projectile assuming there is no air resistance?

Because there is no air resistance to slow it down, the bullet experiences no horizontal acceleration. Thus, the bullet’s horizontal velocity component does not change.

When no air resistance acts on a projectile its horizontal velocity is?

There are no horizontal forces acting upon projectiles and thus no horizontal acceleration. The horizontal velocity of a projectile is constant. there is a vertical acceleration caused by gravity (approx. 10 m/s).

What assumptions need to be made for the the jumper’s trajectory to be purely parabolic in this time interval?

This equation defines the maximum height of a projectile and depends only on the vertical component of the initial velocity.

When air resistance does not affect the motion of a projectile its horizontal and vertical components of velocity remain constant?

In the absence of air resistance there are no forces or components of forces that act horizontally. A velocity vector can only change if there is acceleration (acceleration is the rate of change of velocity).

What is horizontal acceleration of a projectile?

Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero.

Does air resistance affect horizontal velocity?

Air resistance would cause a horizontal acceleration, slowing the horizontal motion, but since we’re going to only consider cases where air resistance is negligible we can assume that the horizontal velocity is constant for a projectile.

Does air resistance affect the trajectory of a projectile?

Furthermore, there is always an initial time interval during which the trajectory is identical to that calculated in the absence of air resistance ( i.e., ). Finally, in the presence of air resistance, the projectile tends to fall more steeply than it rises.

Does the vertical component of a projectile change as the projectile moves?

T/F In the absence of air resistance, the vertical component of a projectile’s velocity does not change as the projectile moves. False At the instant a ball is thrown horizontally with a large force, an identical ball is dropped from the same height.

How do you find the resistive force of a projectile?

Mathematically, the resistive force represented by the vector F can be written as F=-f(v) u, where u=V/|V| is the unit vector along the direction of the velocity V. The minus sign guarantees that the air resistance acting on the projectile is always opposite to the direction of its velocity.

Is air resistance directly proportional to speed?

Suppose, further, that, in addition to the force of gravity, the projectile is subject to an air resistance force which acts in the opposite direction to its instantaneous direction of motion, and whose magnitude is directly proportional to its instantaneous speed.
