What are the factors that we need to be considered for a projectile motion to occur?
In projectile motion, an object moves in parabolic path; the path the object follows is called its trajectory….The key components that we need to remember in order to solve projectile motion problems are:
- Initial launch angle, θ
- Initial velocity, u.
- Time of flight, T.
- Acceleration, a.
- Horizontal velocity, vx.
How projectile motion is used in real life situation?
Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the form of a parabola. This is how the projectile motion is used in real life.
What is the effect of drag on the motion of the projectile?
The projectile is launched at an angle with initial velocity . The force due to air resistance is assumed to be proportional to the magnitude of the velocity, acting in the opposite direction. A significant decrease in the maximum horizontal range is observed when the drag force becomes large.
How projectile motion is affected by gravity?
Gravity will affect a projectile as it will decrease the height the projectile can obtain. The force of gravity acts on the object to stop its upward movement and pull it back to earth, limiting the vertical component of the projectile. As a projectile moves through the air it is slowed down by air resistance.
Can you enumerate some examples of projectile in motion you encountered in your daily life?
Water Escaping a Hose The water coming out of a hose attached to a water source or a water tap follows a projectile motion when it is held at an angle. The path followed by the water is clearly parabolic in nature because it tends to move in a vertical and horizontal direction at the same time.
How can you apply the concept of momentum to everyday life situations?
One example is the use of air bags in automobiles. Air bags are used in automobiles because they are able to minimize the effect of the force on an object involved in a collision. Air bags accomplish this by extending the time required to stop the momentum of the driver and passenger.
What do you mean by an angular projectile give one example from daily life?
A projectile is any object that is cast, fired, flung, heaved, hurled,pitched, tossed, or thrown. you throw the ball straight upward, or you kick a ball and give it a speed at an angle to the horizontal or you just drop things and make them free fall; all these are examples of projectile motion.
What remains 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.
Does lift affect the speed of a projectile?
Because the lift force is perpendicular to the velocity of the object, lift can have no effect on the magnitude of velocity. The magnitude of velocity is also known as speed, so (D) is correct.
What effect does the force of gravity have on the vertical velocity of a projectile?
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 gravity unable to affect in a projectile *?
Gravity opposes the vertical component of velocity of the projectile with which it has been projected. As gravity will affect the vertical component only.
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 best way to analyze projectile motion?
The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical. (This choice of axes is the most sensible, because acceleration due to gravity is vertical—thus, there will be no acceleration along the horizontal axis when air resistance is negligible.)
What is the maximum height a projectile can reach?
Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height of 233 m (neglecting air resistance).
Why is the acceleration of a projectile not constant?
Acceleration for a projectile is proportional to the forces acting on it. These forces are gravity, and friction with the medium through which it moves. Neither of these are constant (except over vanishingly small distances) so the resultant acceleration is not constant either. How come the acceleration in the x-direction = 0 in projectile motion?
