When a ball is thrown straight up by how much does the speed decrease each second neglect air resistance?

Ignoring Air Resistance, on earth near the earths surface gravity applies a force on all bodies.
The acceleration the ball will experience is -9.8 meters per second per second (i.e. it will slow the ball down. When the ball then falls to the ground from the apogee of the throw it will continue to accelerate at 9.8 meters per second per second per second and will hit the ground at the same speed it left the ground originally.
So each second it will slow by 9.8 meters per second.
9.8 meters per second, (or 32.2 feet per second), if the experiment is carried out on or near the surface of the earth.
1.6 meters (5.25 feet) per second, if it's on or near the surface of the moon.
3.52 meters (11.5 feet) per second, if it's on or near the surface of Mars.

What can cause the direction of an object moving in a straight line to change?
The direction of an object moving in a straight line can change due to the application of a force in a different direction, such as friction or a second object interacting with it. Additionally, external factors like gravitational pull or air resistance can also influence the direction of the object.
What is retardation measured in physics?
In physics, retardation refers to the decrease in velocity or speed of an object over time. It is measured in units of acceleration, typically meters per second squared (m/s^2). Retardation can be caused by forces such as friction, air resistance, or gravity.
What is the speed of a 380 acp bullet falling straight down?
The speed at which a .380 ACP bullet falls straight down will be approximately 25-30 feet per second based on gravity (9.81 m/s^2) as it accelerates towards the ground. The speed will increase with time due to gravity pulling it down.
In what order do the effort fulcrum and resistance appear on a second class lever?
On a second class lever, the effort is applied at one end of the lever, while the resistance is located in the middle of the lever, between the effort and the fulcrum.
What is the lever which the effort force is between the resistance force and fulcrum?
This is a second-class lever. The resistance force is located between the effort force and the fulcrum in this type of lever. An example of a second-class lever is a wheelbarrow.
Prove Hall's theorem from Tutte' theorem graph theory?
in this theorem we will neglect the given resistance and in next step mean as second step we will solve
If the larger fish has a mass of 5 kg and swims 1 meter per second toward a 1 kg fish what is the velocity of the larger fish immediately after lunch you will neglect the effects of water resistance?
By conservation of momentum, the total momentum before the lunch equals the total momentum after the lunch. Initially, the total momentum is 5 kg * 1 m/s = 5 kg·m/s, as the smaller fish is initially at rest. After the lunch, since momentum is conserved, the larger fish will have a velocity of 0.2 m/s (5 kg·m/s / (5 kg + 1 kg)).
A ball is thrown straight up from the edge of the roof of a buildinga second ball is dropped from 1sec later ignore air resistance?
... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.
A baseball is hit straight up at an initial velocity of 100 meters per second. What will be the baseball's speed when it hits the ground?
I assume you hit it up from the ground level as well. From Conservation of Energy, it immediately follows that: * If there is no air resistance, when it hits the ground it will, once again, have a speed of 100 meters per second. * Since under usual circumstances there WILL BE air resistance, its speed will be less than 100 meters per second.
What happens to the distance you fall during each second?
If you fall from a very considerable height then initially the distance that you fall will increase with each second that you fall. However, air resistance increases markedly with speed and this causes your acceleration to decrease so that you reach a maximum speed (terminal velocity)

What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.

The second postulate of kinetic theory states that particles move in random straight lines at various velocities and in all directions what is the effect of increasing the temperature of the system?
Decreasing the temperature of the system will decrease the average velocities of the particles, but will not change their pattern of movement.
