Does launch angle affect time?

The time in air is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the time in air.

How can two projectiles launched with the same speed but at different angles have the same range?

Fact is, the range is proportional to the sine of twice the projection angle. So, Because, So, the range of two projectiles is same if their projection angles are complementary.

What angle gives the maximum time for a projectile?

45 degrees
A projectile, in other words, travels the farthest when it is launched at an angle of 45 degrees.

What 2 factors affect flight time of a projectile?

The time it takes from an object to be projected and land is called the time of flight. It depends on the initial velocity of the projectile and the angle of projection. The maximum height of the projectile is when the projectile reaches zero vertical velocity.

How does the launch speed affect the time of flight and range of a projectile?

As it rises and falls, air resistance has a negligible effect. The distance traveled horizontally from the launch position to the landing position is known as the range. The range of an angled-launch projectile depends upon the launch speed and the launch angle (angle between the launch direction and the horizontal).

How does the launch angle affect the distance a projectile travels?

Launching slightly upward will increase the distance because the projectile travels for a longer time. But launching too close to straight up would decrease the distance, since the projectile has no horizontal velocity.

When a projectile is launched horizontally at what point is it at its minimum speed?

Answer: The minimum speed of a projectile occurs at the top of its path. If it is launched vertically, its speed at the top is zero. If it is projected at an angle, the vertical component of velocity is still zero at the top, leaving only the horizontal component.

Why does 30 degrees and 60 degrees have the same range?

An object thrown up into the air at 60 degrees will have the same horizontal distance (or range) as if it were thrown at 30 degrees. The only difference is the height the objects go and the time they are in the air.

At what angle will the projectile have the same range when thrown at an angle of 15 degrees 30 degrees?

3. Answer: B Explanation: A careful inspection of either Figure 1 or Table 1 reveals that the range of a projectile has an identical value for more than one launch angle. For instance, the range is the same for a 15° and a 75° angle. The range is also the same for a 30° and a 60° launch angle.

How does the launched angle affect the distance range of a projectile travels?

Answer: C Explanation: The maximum range occurs for a launch angle of 45°. This highest point increases as the angle increases. At a 75° launch angle, the maximum height is approximately 76 meters. However, a further increase in launch angle beyond this 75° angle will increase the peak height even more.

How does speed of release affect projectile motion?

Because air resistance affects the horizontal component of a projectiles trajectory, the effect of it can be minimized by lowering the angle of release. Speed or velocity is directly related to distance. The greater the speed of release, the greater the distance covered in flight.

What is the range of a projectile with the same launch angle?

Luckily, since the range of our launch angle is 0 ≤ θ 1, θ 2 ≤ 90, it is true that 0 ≤ 2 θ 1, 2 θ 2 ≤ 180. Therefore, for any θ 1, there exists a θ 2 which results in the same projectile range. The only exception to this truth is when θ 1 = 45, at which point θ 2 will also have to be equal to 45.

Why do rocket launches move the launch angle closer to the ground?

Launch angles closer to give longer maximum horizontal distance (range) if initial speed is the same (see figure 5 above). These launches have a better balance of the initial velocity components that optimize the horizontal velocity and time in air (see figure 4). People mix up horizontal vs. vertical components of acceleration and velocity.

What is the horizontal distance travelled by a projectile called?

The horizontal distance travelled by a projectile is called its range. A projectile launched on level ground with an initial speed v0 at an angle θ above the horizontal will have the same range as a projectile launched with an initial speed v0 at 90° − θ and maximum range when θ = 45°. (1 vote)

Why do steeper launch angles increase time in air?

Since steeper launch angles have a larger vertical velocity component, increasing the launch angle increases the time in air. For deeper explanations of the relationship between projectile time in air and initial vertical velocity, see Sal’s video on the optimal angle for a projectile.
