Which Of The Following Ideas Is True About Projectile Motion Without Air Drag? (Best solution)

How much does air resistance influence the velocity of a projectile?

  • In our investigation of projectile velocity, we used the assumption that the effects of air resistance are negligibly tiny. Although air resistance (also known as air drag or just drag) has a significant impact on the motion of numerous things, including tennis balls, bicycle riders, and airplanes, it is sometimes overlooked. When we looked at how a fluid resistance force influenced, we found that it was 5.3.

What is true about the motion of a projectile?

True – Throughout its entire flight, a projectile has a vertical acceleration of 9.8 m/s/s. False This acceleration value is constant throughout the simulation. Each second of motion results in a 9.8 m/s change in the vertical velocity, which indicates that the vertical velocity varies by the same amount each second of motion. With a continuous increase in vertical velocity, the horizontal velocity decreases.

How does air drag affect projectile motion?

Objects traveling through air are slowed down as a result of air resistance, which is also known as drag. When a spacecraft re-enters the Earth’s atmosphere, the air resistance influences not just the course of the spacecraft, but also the path of a projectile such as a bullet or a ball. The maximum height, the maximum range, and the maximum velocity of the projectile are all decreased.

How does no air resistance affect projectile motion?

The gravitational force acts on the item, causing it to cease its upward travel and drag it back down to earth, therefore restricting the vertical component of the projectile’s trajectory. As a bullet travels through the air, it is slowed down by the resistance of the air surrounding it. The horizontal component of a bullet will be reduced as a result of air resistance.

What is the path of a projectile without air resistance?

When there is no air resistance, the horizontal component of a projectile (with respect to the Earth) remains constant while it travels into space. As time progressed, the vertical component of the wave would rise in the direction of the gravitational field. This results in a perfectly symmetrical parabola.

Which of the following statement is true about horizontal projectile motion?

A projectile having a horizontal component of motion will have a constant horizontal velocity because of the horizontal component of motion. It is always the case that the end horizontal velocity of a bullet equals the starting horizontal velocity.

Which of the following describes a projectile motion?

It is the motion of an item that has been hurled or projected into the air that is subjected to nothing but the acceleration of gravity that is called projectile motion. The item is referred to as a projectile, and the course it takes is referred to as a trajectory.

What affects projectile motion?

Gravity is one of the factors that affects the flight path of a projectile. Air Resistance is a term used to describe the resistance created by air. Release at a rapid pace. Release at an oblique angle.

How does drag affect velocity?

When dealing with low-speed flow, the drag force is proportional to the velocity, and when dealing with high-speed flow, the drag force is squared the velocity, where the differential between low and high speed is measured by the Reynolds number. Drag forces usually have a tendency to lower fluid velocity when compared to the velocity of a solid object in the path of the fluid.

Does projectile motion have air resistance?

Consider the possibility that, in addition to the gravitational force, the projectile is subjected to an air resistance force that operates in the opposite direction of its instantaneous direction of travel and whose magnitude is directly proportional to its instantaneous velocity.

What does it mean if there is no air resistance?

Air Resistance is a term used to describe the resistance created by air. When an item falls against air resistance, the object’s acceleration and speed alter as it moves through the air. When an object falls in a vacuum, there is no air resistance to prevent the object from falling since there is no air present in a vacuum. Using air resistance, a rock and a feather are launched from the same height and distance from rest respectively.

When no air resistance acts on a projectile Its acceleration is?

What is the vertical acceleration of the object if you ignore air resistance? Is it because of horizontal acceleration? Because the force of gravity is directed downward, it has a vertical acceleration of g. Its horizontal acceleration is zero since it is not subjected to any horizontal forces.

What happens in the absence of air resistance?

When dropped from the same height, heavy things arrive at the ground at the same time as lighter objects since there is no air resistance to slow them down (Figure). The gravitational pull of the Earth causes items to fall toward the center of the planet. As a result, the acceleration of free-falling objects is referred to as “gravitational acceleration.”

What are the 3 types of projectile motion?

Projectile Motion can be classified into the following types:

  • Projectile motion may be classified into the following categories: (1) oblique projectile motion
  • (2) horizontal projectile motion
  • (3) projectile motion on an inclined plane.

Which statement is true when the projectile is at the highest point?

When the bullet reaches the highest point of its trajectory, the velocity of the projectile is perpendicular to the acceleration of the projectile, as shown in the diagram. Its velocity and acceleration are both equal to zero degrees per second.

What is the motion of a projectile in free fall characterized by?

Even though it does not exist at the start, it expands in size as the item descends. An object in free fall has a continuous downward acceleration as it moves vertically, which is known as the vertical motion of a projectile. Once launched, a projectile is propelled forward by the force of its own inertia and is only impacted by the downward force exerted by gravity.
