A projectile fired from the ground follows a parabolic path The speed of the projectile is minimum at the top of its path?
Yep that is correct. To understand this it may help you to draw a parabola. If you draw a line from the top of the parabola back to the ground you'd notice either side of this line is symmetrical. This isn't quite what happens to a projectile (following a parabolic path), but because of the nature of the question, effects such as air resistance can be ignored.
As the projectile approaches the top of its path, the vertical component of its velocity approaches zero. As the projectile begins to fall the magnitude of the vertical component of the projectile begins to increase. The only force that acts on the projectile during flight is gravity which pulls it towards the earth. Since this force and the horizontal component of the projectiles velocity are at right angles to each other, the horizontal component of the velocity is unaffected during flight . This explains the symmetry of the parabola and also means the time to reach the top of path equals the time from the top of path back to the ground.
The projectile will hit the ground with the same speed as it left the ground. If you draw a horizontal line through the parabola, at the two points where the line and the parabola cross, the speed of the projectile will be the same. The only change to the balls speed during the flight comes as the vertical component of its velocity tends to zero as it reaches the top of the curve and then falling back down due to gravity.
I'm unsure of your physics knowledge but hopefully this doesn't confuse you. If you have learned about vectors, then this can be simply understood/explained.

What specific path is traced by each fragment of a firework?
Each fragment of a firework follows a parabolic path once ignited. After the firework is launched, the explosive force propels the fragments upwards before gravity takes over, causing them to arc back down towards the ground.
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.
What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
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).
Is aerial tumbling best example of projectile principle for height?
Yes, aerial tumbling is a good example of the projectile principle for height. This is because the performer launches themselves vertically, experiences a free-fall phase, and then lands back on the ground. The height achieved during the tumbling routine is a result of the initial vertical launch and the influence of gravity on the performer's trajectory.
What is projectile trajectory?
A projectile's trajectory is the curve along which it moves through the air or space. When a projectile is fired on earth the simplest theory holds that its trajectory will be parabolic in form. However, this does not account for air resistance and other factors.
What is half projectile?
A half projectile refers to the projectile motion of an object where it is launched at an angle of 45 degrees to the horizontal. This angle maximizes the range of the projectile for a given initial velocity, making it travel the furthest distance before hitting the ground. The path of the projectile is a parabolic curve.
What is the curve described by a projectile in fights?
The curve described by a projectile in flight is called a parabolic trajectory. This curve is a result of the combined effects of the projectile's initial velocity, launch angle, and the force of gravity acting upon it. The projectile follows this path as it moves through the air until it eventually falls to the ground due to gravity.
What is a freely falling projectile?
A freely falling projectile is an object that is only acted upon by gravity, moving through the air in a parabolic path while falling towards the ground. It does not have any initial horizontal force or acceleration other than gravity acting upon it.
A sepak takraw that is kicked from a height of two meters follows a path that is?
parabolic, defined by the shape of a quadratic equation, where the ball's trajectory will form a curve in the shape of an inverted "U." It will reach its peak height midway before descending back to the ground. The path can be calculated using projectile motion equations to determine the distance traveled and time of flight.
Is a ball on the ground a projectile?
No, a ball on the ground is not considered a projectile. In physics, a projectile is an object that is in motion and is only subject to gravity and air resistance. A ball on the ground is not in motion and is not being acted upon by external forces.
At what height h above the ground does the projectile have a speed of 0.5v?
The projectile has a speed of 0.5v at a height h above the ground.
How will a ball falling fom train appear to a passenger on train and a man standing on ground?
To a passenger on the train it will follow a parabolic trajectory facing towards the back of the train. To a man standing on the ground it will be a forward facing parabolic trajectory.
What are the two components of a projectile?
The two components of a projectile are the horizontal component, which determines the distance the projectile travels, and the vertical component, which influences the projectile's height and the time it takes to reach the highest point and return to the ground.
What is the path of projectile in vacuum?
In a vacuum, the path of a projectile is a parabolic curve determined by its initial velocity and angle of projection. The projectile follows a trajectory where only the force of gravity affects its motion, resulting in a symmetrical path as it rises, then falls back to the ground.
With out air pressure at what point or points in its path does a projectile have its minimum speed and its maximum?
Without air friction, the horizontal component of the velocity will be constant. The vertical component of the velocity will be a maximum at the lowest point in its motion and at a minimum at the highest point in its motion. Therefore the minimum is at the highest point in its motion- Potential energy max Kinetic Energy min and the maximum is at its lowest point in the motion- KE is max PE min
Why motion of body thrown from a certain height?
The motion of a body thrown from a certain height can be described by the laws of projectile motion, where the object follows a curved path due to the combination of its initial velocity and the force of gravity. As the object moves through the air, it experiences acceleration towards the Earth, resulting in a parabolic trajectory until it eventually reaches the ground.
