What else can I help you with?
A projectile has been fired horizontally from the top of a building 40 m high neglecting air resistance what is the magnitude of its acceleration in the vertical direction in ms2?
The acceleration in the vertical direction for the projectile fired horizontally is -9.81 m/s^2. This is because the only force acting on the projectile in the vertical direction is gravity, causing it to accelerate downward at a rate of 9.81 m/s^2.
How those air resistance affect the vertical and horizontal velocity of a projectile calculation?
Air resistance will slow down both the vertical and horizontal velocity of a projectile. In vertical motion, it will decrease the upward velocity and decrease the time the projectile spends in the air. In horizontal motion, it will reduce the forward velocity and cause the projectile to fall short of its ideal range.
Does the horizontal motion affect the vertical motion of a projectile?
No, horizontal motion does not affect the vertical motion of a projectile. The two components of motion (horizontal and vertical) are independent of each other in the absence of external forces such as air resistance. The vertical motion is governed by gravity, while the horizontal motion remains constant.
Is projectile motion a motion in one-dimension-the direction of gravity?
No. Neglecting air resistance, the projectile follows a parabola. The horizontal distance is proportional to 'time', and the vertical distance is proportional to 'time squared'. This is exactly the description of a parabola.
Which two forces affect the motion of a projectile?
The two forces that affect the motion of a projectile are gravity and air resistance. Gravity acts to pull the object downward, influencing its vertical motion, while air resistance affects the projectile's horizontal motion by slowing it down as it travels through the air.
What part of projectile motion is affected by gravity?
Gravity affects the vertical component of projectile motion by causing the object to accelerate downward as it moves horizontally. This acceleration due to gravity affects the object's vertical displacement and velocity. It does not affect the horizontal component of projectile motion, which moves at a constant velocity in the absence of air resistance.
How does lateral displacement affect the trajectory of a projectile?
Lateral displacement, or the horizontal distance a projectile travels from its initial path, does not affect the trajectory of a projectile in terms of its vertical motion. The vertical motion of a projectile is determined by gravity and initial velocity, while the horizontal motion is affected by factors such as wind resistance and launch angle. Therefore, lateral displacement does not change the overall trajectory of a projectile.
What is true statement about projectiles?
A true statement about projectiles is that they follow a curved trajectory known as a parabolic path when launched into the air, influenced primarily by gravity and initial velocity. The horizontal motion of a projectile is constant, while its vertical motion is affected by acceleration due to gravity. This means that, neglecting air resistance, the horizontal and vertical motions are independent of each other.
What effect does mass have on projectile motion?
The mass of a projectile has no direct effect on its horizontal motion in projectile motion. However, a heavier mass may affect the projectile's vertical motion by influencing factors such as initial velocity, air resistance, and gravity, which can impact its trajectory.
Is projectile motion a motion in one dimension the direction of gravity?
No, projectile motion involves motion in two dimensions - one horizontal and one vertical. The vertical motion is affected by gravity, while the horizontal motion is independent of gravity, assuming no air resistance.
Example of a parabolic graph of distance versus time?
The vertical distance of a heavy projectile. Heavy so that air resistance can be ignored.
What projectile angle will get you the longest distance?
The optimal launch angle for the longest distance of a projectile is 45 degrees in the absence of air resistance. This angle allows for the greatest horizontal distance because it balances the vertical and horizontal components of the projectile's velocity.
