well in order to calculate the speed of the object at the start point you need to know:
# mass/weight of the object
# the air resistance # the angle
# the form of the object
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
The speed of an object at any instant in time is its instantaneous speed.
When a moving object is pushed in the direction of its motion the speed of the object increases
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
the object's 'velocity'
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
Pitch, or the angle at which an object is thrown, can affect the speed of the object by changing the trajectory and force applied to it. A higher pitch can result in a faster speed due to the increased force and angle of projection.
an object thrown into the air will slow down as it ascends higher into the air until it stops ascending and the speed of the object increases as it falls until it reaches its terminal velocity in air. As an object passes through air, it encounters air resistance which slows down an object moving freely through air. An object will be moving at a slower speed when it hits the ground than it did when it was thrown into the air due to this air resistance.
The instantaneous speed of an object at its highest point when thrown straight up in the air is zero. At the highest point, the object has momentarily stopped moving upwards and is just about to start falling back down due to gravity.
When an object is thrown in space, it will continue moving in a straight line at a constant speed unless acted upon by another force. This is due to the absence of air resistance and gravity in space.
To find the speed at which the object was thrown upward, we need to know the acceleration due to gravity. Assuming g ≈ 9.81 m/s², the initial speed of the object can be calculated using the equation v = u - gt, where v is the final speed (0 m/s when it returns), u is the initial speed, g is the acceleration due to gravity, and t is the time (6 seconds). This calculation will give you the initial speed at which the object was thrown upward.
The instantaneous speed of the object at its highest point is zero. At that moment, the object is at rest before it starts to fall back down due to gravity.
No. Regardless of its initial speed, the object still experiences downward acceleration at the rate of 'G'.
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
Yes. Acceleration is independent of speed. A perfect example of an object with zero speed but nonzero acceleration is an object at the apex of being thrown upward. The entire time it is in the air it is accelerating downward. At its maximum height its speed is zero.
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
Radar was first used to measure the speed of a moving object in 1935. By 1938, they were used to measure the speed of a fastball thrown by Bob Feller.
