It isn't. Any projectile path is elliptical or round. One-half of an ellipse in polar coordinates mapped (not just converted) into Cartesian coordinates is a parabola. If you get this far, any projectile path on a spherical Earth's surface would be elliptical, but if you turned the Earth inside out, the path would be hypocycloidal. Hope this helps. ===========================================
??? An ORBIT is elliptical. But the behavior of an ordinary projectile over non-planetary distances is effectively that of an object launched at an angle with regard to a plane in a uniform gravitational field - over short distances the earth's surface is reasonably close to a plane and gravity acts essentially perpendicular to that plane. So, an object launched at an angle θ with a velocity of vo moves in two dimensions. It has a constant velocity vo * cos(θ) horizontally and a downward acceleration that's proportional to sin(θ) and the acceleration of gravity g.
The constant horizontal velocity means that the horizontal (x-axis) distance covered is directly proportional to the flight time, while the accelerating vertical velocity means the vertical (y-axis) distance is proportional to the square of the flight time. But that's exactly the relationship that describes a parabola; i.e. y = kx2
Yes, the shape of the path followed by a projectile in a uniform gravitational field is a parabola. This is due to the fact that the motion of the projectile can be broken down into independent horizontal and vertical components, resulting in a parabolic trajectory.
The projectile doesn't act as a parabola, but a graph of the magnitude of its
velocity vs time does.
In projectile motion, the horizontal component of velocity is constant and the
vertical component is accelerated. The 2-dimensional resultant of one constant
component and an accelerated one is a parabola.
It will only approximate a parabolic path (you have to ignore the effect of air resitance, the coriolis effect, the reduction of gravity at higher altitudes etc.) If we do ignore all these (rater small) effects the simple answer is that there is a gravitational field that operates on the projectile. The initial velocity of the projectile is acted upon by the vector of gravity.
Parabolic Path of a Projectile
Easily:
In the vertical direction
F=ma=md2ydt2=−mg
Integrated twice we obtain
y(t)=y(0)+vy(0)t−12gt2
Which is indeed the equation of a parabola with respect to time.
Now in the x-direction, we have
x(t)=x(0)+vx(0)t
since there is no force in this direction. It should be clear that if we re-write y(t) in terms of x(t), by solving for t in the above equation, y(t) will also be a parabola in terms of x.
It is, to a first approximation, assuming air resistance can be neglected, and assuming the path is relatively short. Actually, any object moving around Earth travels in an ellipse; so the parabola is only an approximation - valid if you consider Earth's surface to be flat, and gravity not to change with altitude.
The gravitational attraction on the projectile will pull it pack down to Earth.
The path of a projectile is a parabola. This is a two dimensional motion.
Its trajectory.
Yes, that is usually correct.
The path of a projectile is a parabola because the force of gravity acts perpendicular to the initial velocity, causing the projectile to follow a curved trajectory. This curved path results from both horizontal and vertical motion, creating a parabolic shape.
projectile motion
A projectile follows a curved path called a parabola when it is launched horizontally or at an angle in the air. This path is a result of the combination of the projectile's initial velocity and the force of gravity acting on it. The shape of the path may vary depending on the launch angle and velocity of the projectile.
A projectile follows a parabolic trajectory due to the influence of gravity, which causes it to accelerate downwards. The initial horizontal velocity of the projectile allows it to travel horizontally while falling vertically, resulting in a curved path known as a parabola.
A curved path followed by a projectile is called a trajectory. This is the path that an object takes when it is thrown or launched into the air.
Trajectory is the path a projectile follows Parabola is the shape of this path
The path of a projectile in earth gravity is that of a parabola.
projectile motion
A projectile following a parabolic path on a circle can be understood as the motion of an object launched at an angle along the circumference of the circle. As the object moves, gravity causes it to follow a parabolic trajectory while the curvature of the circle influences its path. The resulting motion combines the circular motion of the circle with the parabolic motion of the projectile.
An object projected by force and continuing in motion by its own inertia.An objectile is a a projectile only when it is in a state of motion,usually it covers a parabola shape path.
False. A projectile is an object that is thrown or launched into the air and has a parabolic trajectory. A cannonball rolling down a slope is not considered a projectile because it is not launched into the air.
a parabola
A curved path followed by a projectile is called a trajectory. This is the path that an object takes when it is thrown or launched into the air.
A parabola is the curved path of a projectile is the result of constant motion horizontallt and accelerated motion vertically under the influrnce of gravity.
The curved path an object follows when thrown is called a projectile motion. It is a combination of horizontal motion (due to initial velocity) and vertical motion (due to gravity). The object follows a parabolic trajectory as it moves through the air.
A projectile follows a curved path known as a parabola in the absence of air resistance. This path is due to the combination of the projectile's initial velocity and the acceleration due to gravity acting on it.
Physics projectile motion is the motion of an object that is projected into the air and then moves under the influence of gravity. The object follows a curved path known as a trajectory, exhibiting both horizontal and vertical motion. The key factors affecting projectile motion are the initial velocity of the object, the angle at which it is launched, and the force of gravity.
