True or false Independent of initial velocity a projectile will always fall back to the surface of the planet it is launched from?
Diann1458
True, at relatively low speeds, if the projectile was launched at maybe the speed of light, improbable as it is, this may give it enough momentum to carry on past the point were the planet's gravity has a large effect on its motion and therefore carry on moving away from the planet until stopped by another force, however, even if the initial velocity of the projectile is the same as that planets escape velocity (the speed it needs to travel at to leve the planet) this speed is not constant and the projectile will feel a very large force from the gravity of the planet and hence be brought back down to its surface

Why projectile angle increase when projectile range also increase?
Range of a projectileThe path of this projectile launched from a height y0 has a range d.In physics, a projectile launched with specific initial conditions in a uniform gravity field will have a predictable range. As in Trajectory of a projectile, we will use:g: the gravitational acceleration-usually taken to be 9.80 m/s2 (32 f/s2) near the Earth's surfaceθ: the angle at which the projectile is launchedv: the velocity at which the projectile is launchedy0: the initial height of the projectiled: the total horizontal distance travelled by the projectileWhen neglecting air resistance, the range of a projectile will beIf (y0) is taken to be zero, meaning the object is being launched on flat ground, the range of the projectile will then simplify toso to increase the range θ shoud vary from 0 to 45 and after 45 it starts decreasing.
How far below an initial straight line path will a projectile fall in one second?
Given no air resistance or other forces acting on the projectile, the projectile falls at a rate of ~9.81 meters per second. Given the position equation is at^2 + vt + x, where a is acceleration, v is velocity, x is the starting position, and t is time. Given an initial velocity and time of zero, the object will have moved ~9.81 meters in the first second.
How do you calculate range of projectile from ground at A degrees if you know its range is 200 meters if its launched from height of 2 meters at A degrees?
You cannot. You need to know either the initial speed or angle of projection (A).
If an object is accelerating what equation relates the distance traveled by that object to the initial velocity final velocity and time?
Final velocity = Initial velocity +(acceleration * time)
What is acceleration of a body moving with uniform velocity?
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
What makes up a projectile motion?
Some of the factors that determine the movements of a projectile include: air resistance, force of gravity, initial launch velocity, the angle a projectile was launched at, and the objects initial elevation.
What do you you need to know to determine how far a projectile travels horizontally?
initial velocity, angle of launch, height above ground When a projectile is launched you can calculate how far it travels horizontally if you know the height above ground it was launched from, initial velocity and the angle it was launched at. 1) Determine how long it will be in the air based on how far it has to fall (this is why you need the height above ground). 2) Use your initial velocity to determine the horizontal component of velocity 3) distance travelled horizontally = time in air (part 1) x horizontal velocity (part 2)

A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
Which information is needed to find the time a projectile is in motion?
The object's initial distance above the ground The object's initial velocity
What is the projectile theory?
if a body is thrown having initial velocity and make angle with ground this body is known as projectile and the way is calle trajectory
How to find the height of the projectile launch if the angle velocity and the distance are given?
Get the value of initial velocity. Get the angle of projection. Break initial velocity into components along x and y axis. Apply the equation of motion .
