As a ball goes up, the force of gravity is acting on it. The force of gravity means that acceleration in the upward direction is negative (and thus positive in the downward direction). The upward velocity of the ball decreases until it reaches zero - then ball begins to descend with increasing downward velocity.
What else can I help you with?
Do all balls at the same speed?
No, not all balls move at the same speed. Factors such as weight, surface texture, and the force of the impact can affect how fast a ball moves. Balls with different properties will have different speeds when thrown or hit.
How does speed effect lift?
An increase in speed typically leads to an increase in lift generated by an airfoil. This is because higher speeds result in a higher pressure difference between the upper and lower surfaces of the wing, which in turn creates more lift. However, excessive speed can also lead to aerodynamic stalls or other issues that may reduce lift.
Does traveling at a high speed require greater stopping distance?
Yes, traveling at a higher speed increases the kinetic energy of the vehicle, which means it will require a greater stopping distance to come to a complete stop. This is because the vehicle needs more time and distance to reduce its speed gradually.
When two balls of different masses are thrown upwards Which ball will pass through the point of projection in the downward direction at a faster speed?
Assuming both are released with the same initial velocity and not of extremely light weight the smaller mass will be thrown higher. Since they both fall with an acceleration of 32 feet per second squared the smaller mass has more time to gain speed and will have a higher velocity when it passes the point of release.
Why road accidents at high speed are worse?
Road accidents at high speed are worse because the force of impact is greater, causing more severe damage to vehicles and occupants. High-speed accidents also reduce the time available for drivers to react and take evasive actions, increasing the likelihood of a collision. The higher speed can lead to more violent crashes and a higher chance of fatalities or serious injuries.
What speed rocket starts?
A rocket's speed at launch is typically zero, as it starts from a stationary position on the ground. The rocket gradually accelerates as it is propelled by its engines, reaching higher speeds as it ascends into space.
How do you increase the speed of a motorcycle?
You can change the chain sprockets of most motorcycles to get a higher top speed. Reduce the rear sprocket numerically, and/or increase the front sprocket numerically. A higher profile tire will also increase top speed slightly.
What is the best ball for distance?
This all depends on your swing speed my friend. Harder balls go farther for a person with higher swing speeds and softer balls go further for those individuals with lower swing speeds.
How can an aircraft reduce the speed in the air?
during flight aircraft reduce speed by spoiler
What happens when the mass of either the balls is increased in simulation?
the balls decrease in speed
What should you do when operation a boat in large waves and high wind?
head into the waves at a slight angle and reduce speed
Do all balls at the same speed?
No, not all balls move at the same speed. Factors such as weight, surface texture, and the force of the impact can affect how fast a ball moves. Balls with different properties will have different speeds when thrown or hit.
What is engine braking on a Lexus hybrid?
Engine Brake: One way to reduce speed by shift down the gear from Higher to Lower (Eg. Driving with 120 km/h with 5th gear, by turning to Engine Brake it reduce to 4th gear that make the speed is reduced) It's very helpful when driving with high speed.
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.
Why worm is geared with worm gear Give reasons?
A worm or machine can be geared with worm gear to give it higher torque or to reduce rotational speed in the machine.
What does reduce engine speed mean in a 2002 Chevy Tahoe?
It means some one has programmed a speed limit in the vehicle. If the vehicle exceeds the preset speed it will warn you to reduce speed.
Motorway speed limits are reduced in France when weather is bad to reduce accidents though normally their speed limits are higher than in Britain. What are the advantages and disadvantages of this?
The advantage is that people get where they are going faster. The disadvantage is that crashes are more likely, and therer will be a higher risk of serious injury or death.
