The following description covers the region near the surface of the earth ... the neighborhood we live in. It also talks about objects that are just coasting, i.e. no strings attached, no propellers, jets, rockets etc. An object moving upward with no force on it other than gravity will 'decelerate', that is, its speed will decrease at the rate of 32 ft per second slower every second, until its upward speed is zero. From that instant, it will begin falling downward, just as if it had been dropped from that height, and its downward speed will begin to grow, at the rate of 32 ft per second faster every second.
What else can I help you with?
Why do falling objects move faster than objects going upward?
Falling objects are accelerated by gravity, while objects moving upward are being decelerated by gravity. Gravity pulls objects downward, increasing their speed, while it opposes the motion of objects moving upward, decreasing their speed.
When a coin is tossed upward as it is ascending what happens to its velocity?
As the coin is tossed upward, its velocity decreases due to the pull of gravity working against it. At the peak of its ascent, the velocity momentarily drops to zero before it starts descending back down.
Why do objects fall to the ground when thrown upward?
Objects fall back to the ground when thrown upward due to the force of gravity acting upon them. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downwards. When an object is thrown up, it loses its upward velocity and gravity then pulls it back towards the ground.
What is downward velocity?
Downward velocity refers to the speed at which an object is falling towards the ground or moving in a downward direction. It is commonly measured in units such as meters per second or feet per second. A positive downward velocity indicates the object is accelerating downward, while a negative velocity means the object is moving upward.
What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.

How can tornadoes pick stuff up?
Air in a tornado moves upward pretty rapidly. This upward moving wind often carries objects with it.
When will objects thrown upward start to go down?
When the vertical component of their velocity has dwindled to zero because of the acceleration of gravity.
Why do objects fall to the ground when thrown upward?
Objects fall back to the ground when thrown upward due to the force of gravity acting upon them. Gravity is a force that pulls objects towards the center of the Earth, causing them to accelerate downwards. When an object is thrown up, it loses its upward velocity and gravity then pulls it back towards the ground.
What is downward velocity?
Downward velocity refers to the speed at which an object is falling towards the ground or moving in a downward direction. It is commonly measured in units such as meters per second or feet per second. A positive downward velocity indicates the object is accelerating downward, while a negative velocity means the object is moving upward.
What is the velocity of a ball thrown upward at 16 feetsec?
The velocity of the ball is 16 feet/sec when it is thrown upward.
Is an upward moving object experiencing an upward force?
If the object is moving upwards with a constant velocity, there is only one arrow in the diagram, and it points straight down, due to gravity. If it has a force pulling upward on it, there are two arrows, one up, due to the force, and one down, again, due to gravity.
When is the veritical velocity decreases to zero?
Vertical velocity decreases to zero at the highest point of an object's trajectory when it momentarily stops moving upward before falling back down due to gravitational pull.
Give an example in which velocity is zero yet acceleration is not zero?
Velocity is directional, so if something is accelerating in the opposite direction from the one it is moving it, there will come a point where it has 0 velocity but still has accelerating. If you throw a ball at the ground and it bounces, for example.
What is an upward moving current of air?
An upward moving current of air is called an updraft.
What does an upward sloping diagonal line mean in position vs time graph?
It means that either the distance is measured from the starting-line and the object is moving forward, or else the distance is measured from the finish-line and the object is moving backwards, because the distance is growing as time goes on. If the upward sloping diagonal line is straight, it means the speed is constant. (not velocity)
