Other Related Questions on Mechanics. Why does the projectile have no acceleration in the horizontal direction? 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 vertical velocity of a projectile changes by 9.

Why is there no horizontal acceleration? The horizontal acceleration is zero for projectile motion because there is no force acting on the projectile that would produce any acceleration in the horizontal direction. Acceleration is the result of a net force acting on an object. What is the acceleration in the horizontal direction during projectile motion?

For the horizontal motion of a projectile, there is a zero acceleration. What is horizontal acceleration of a projectile? Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero. There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, There is a vertical acceleration caused by gravity; its value is 9. Since, the velocity is constant in horizontal direction so the rate of change of velocity i.

Horizontal motion is defined as a projectile motion in a horizontal plane depending upon the force acting on it. For a short distance, the vertical and horizontal components of a projectile are perpendicular and independent of each other.

Motion in a plane is also called a motion in two dimensions. The horizontal velocity remains constant, because there is no acceleration in that direction. At the highest point, only the horizontal component of velocity is present and the vertical component is zero. The initial horizontal velocity can also be determined by measuring the diameter d of the ball and dividing by the time t that it takes for the ball to move across the photogate.

However, the horizontal component of its velocity is not zero. These concepts are further illustrated by the diagram below for a non-horizontally launched projectile that lands at the same height as which it is launched.

The above diagrams, tables, and discussion pertain to how the horizontal and vertical components of the velocity vector change with time during the course of projectile's trajectory. Another vector quantity that can be discussed is the displacement. The numerical description of the displacement of a projectile is discussed in the next section of Lesson 2. Physics Tutorial.

Student Extras. What is a Projectile? We Would Like to Suggest Sometimes it isn't enough to just read about it. You have to interact with it! And that's exactly what you do when you use one of The Physics Classroom's Interactives. We would like to suggest that you combine the reading of this page with the use of our Projectile Motion Simulator. You can find it in the Physics Interactives section of our website. The simulator allows one to explore projectile motion concepts in an interactive manner.
