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.
A stone is thrown upward from a roof at the same time as another identical stone is dropped from there What is true of the two stones?
A) the dropped one hits the ground first B) the tossed one hits harder
How many forces act on an upwardly tossed coin when it gets to the top of its path, and how do these forces affect its motion?
At the top of its path, an upwardly tossed coin experiences two forces: gravity pulling it downward and air resistance pushing against its upward motion. These forces can slow down the coin's upward movement and eventually cause it to fall back down.
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.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
If air resistance can be neglected, the acceleration of a ball tossed straight upward is the same as when it is dropped - both experience a gravitational acceleration of 9.81 m/s^2 downward. The initial velocity of the tossed ball would cause it to momentarily counteract the acceleration and then eventually slow down and reverse direction due to 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.
Does sound tend to bend upward or downward when it travels faster near the ground than higher up?
Sound tends to bend upward when it travels faster near the ground than higher up. This phenomenon, known as positive refraction, occurs when sound waves are refracted upward due to a decrease in temperature near the ground.
When a falling object hits the ground does the ground apply an upward force?
Yes, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. When a falling object hits the ground, the ground applies an upward force on the object, resulting in the object coming to a stop.
Toss a ball upward what is the change in speed each second on the way up and on the way down?
The change in speed each second when the ball is tossed upward will decrease by 9.8 m/s each second due to gravity until it reaches its highest point and starts falling back down. On the way down, the speed will increase by 9.8 m/s each second as gravity accelerates the ball towards the ground.
Why does not this force lift you the earth upward?
The upward force balances exactly you weight so the resultant force is zero and you stay on the ground, fortunately!
What is upward pull?
ITS LIKE WHEN THERE IS A STICK STUCK DOWNWARD INTO THE GROUND AND YOU WANT TO TAKE IT OUT. YOU WILL PULL IT UPWARD. Sorry for capitalisation.. Hope this helped, :D
What is the distance between the stratosphere and ground in km?
extend upward to about 50 km
