Why is the Y component of a projectile always changing?
In case of projectile motion the vertical component of particle’s velocity changes continuously because of the force acting in vertical direction which is its own weight ( mg ). object ; its horizontal velocity remains constant.
What does Y represent in projectile motion?
The x component is the horizontal motion of the projectile, and the y component is the vertical motion of the projectile. The units to express the horizontal and vertical distances are meters (m). The horizontal and vertical velocities are expressed in meters per second (m/s).
Which factor is most important in projectile motion?
There are 3 factors that are most important in projectile motion:
- The projection angle.
- The magnitude of projectile velocity.
- The height of the projection.
What happens to the y component of velocity as projectiles travel?
The acceleration and velocity in the Y direction is independent of the acceleration (if any) and velocity in the X direction. Realize that while gravity (acceleration) acts on the projectile in the vertical direction, it does not affect the velocity of the projectile in the horizontal direction.
What will be the y component of the ball’s acceleration at the highest point in its trajectory?
The y component of the acceleration ay is the downward acceleration due to gravity. If the path or trajectory of the projectile is near the earth’s surface, ay has a magnitude of 9.80 m/s2.
What force acts in the Y direction that causes an object to travel in a parabolic arc?
In conclusion, projectiles travel with a parabolic trajectory due to the fact that the downward force of gravity accelerates them downward from their otherwise straight-line, gravity-free trajectory.
How do you find y in projectile motion?
Defining the positive direction to be upward, the components of acceleration are then very simple: a y = − g = −9.8 m / s 2 ( − 32 ft / s 2 ) . a y = − g = −9.8 m / s 2 ( − 32 ft / s 2 ) . Using this set of equations, we can analyze projectile motion, keeping in mind some important points.
What factors affect the motion of a projectile?
Factors affecting the flight path of a Projectile are:
- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.
What factors affect the motion of a projectile How do these factors affect a projectile?
FACTORS AFFECTING PROJECTILE MOTION There are three main factors that affect the trajectory of an object or body in flight: the projection angle, magnitude of projection velocity and height of projection.
What force acts in the Y direction that causes a projectile to travel in a parabolic arc?
Gravity causes a vertical acceleration. The ball will drop vertically below its otherwise straight-line, inertial path. Gravity is the downward force upon a projectile that influences its vertical motion and causes the parabolic trajectory that is characteristic of projectiles.
Why is projectile motion important?
The projectile motion emphasizes one important aspect of constant acceleration that even constant acceleration, which is essentially unidirectional, is capable to produce two dimensional motion. The basic reason is that force and initial velocity of the object are not along the same direction.
