Why doesn't a steel ball have 5 times the acceleration of a plastic ball if the steel ball has 5 times the mass and weight of the plastic ball plus if gravity pulls 5 times harder on the steel ball?
We know that Force=mass*Accelaration Acceleration=Force/Mass So,Accelaration is inversely proportional to mass.i.e,if mass increases,acceleration decreases and vice versa . now coming to the present problem, steel ball has more mass than plastic ball so as described above steel ball has less acceleration than plastic ball.
If a ball rolls down a hill does its speed or acceleration increase?
If you roll a ball up a hill it undergoes negative upward and positive downward acceleration.
When a ball is traveling at a constent speed around the inside of circular structure is the ball accerlerating?
Yes, acceleration is present. Acceleration is a change in speed and/or direction of motion. Even if speed is constant, acceleration is present if the path of the motion is anything but straight.
What is the speed and acceleration of a ball rolling down a hill?
The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration.
When you catch a ball it creates a force on your hand the reaction force is?
-- When you catch a ball, you have to change its speed from something to nothing. -- That requires acceleration, and acceleration requires force. -- The force that changes the speed of the ball from something to nothing comes from the muscles in your catching arm.
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
Does the speed of a ball increase or decrease after it hits the ground?
Once a ball has fallen a distance through the air, and it contacts the ground, its speed will rapidly decrease until it has stopped moving. The acceleration experienced by the ball is so great that it seems to stop instantly. Most likely, it will bounce back up, and then repeat this cycle a few times before coming to rest.
When a ball increases in speed by the same amount each second its acceleration is?
... is said to be constant.
What happens to the speed and acceleration of a ball rolling down an irregular slope?
The answer will depend on the shape of the slope, and the trajectory that the ball follows.
If you double the force you throw a ball the acceleration will double?
No. For a start, you probably don't mean "acceleration" you probably mean "speed" or "velocity." There is a non-linear relationship between force applied on an object and the speed which it will travel through a medium (in this case, air). To double the speed, the amount of force required is more than double, since as the speed of the object increases, the frictional losses similarly increase. Since in this case, the ball will continue to slow immediately after release, the ball is experiencing "acceleration" with a negative value. A In case you are really asking about acceleration the answer is yes. If the ball, in your hand, starts from rest and is accelerated up to some velocity at which it leaves your hand then that acceleration will be double if you throw with twice the force. This will cause the ball to leave your hand with twice the velocity. Once it leaves your hand you are no longer exerting a force on it and the ball will be subject to air resistance which will affect its velocity as described above.
A tennis ball and a solid steel ball the same size are dropped at the same time which ball has the greater force acting on it?
If both balls are exactly the same size, and one having larger mass, the 300g ball will hit the ground first. This is easy to relate to a hammer and a large feather, even if they have the same surface area the hammer having a larger mass has a larger terminal velocity.
A ball starts at rest accelerates uniformly and travels 250m in 5 seconds What is the final velocity and the acceleration of the ball?
Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
