Why is the acceleration of gravity the same for both a cannonball and a tennis ball?
Wiki User
∙ 7y ago
KE = 1/2mv2, where m is mass in kg, and vis velocity in m/s. In order for both the tennis ball and Basketball to have the same amount of kinetic energy, their masses and velocities would need to be such that they equal the same kinetic energy.

∙ 12y agoThe acceleration of gravity is constant because it is the ratio of Force over mass. Although the mass of a cannonball is much larger than that of a tennis ball, the force applied to the cannonball is larger than that applied to the tennis ball by the same amount as the ratio of the two masses. The statement is just another way of saying that the gravitational pull of an object is directly proportional to the object's mass.

∙ 13y agoIf there velocities differ and are related such that v1=sqrt((m2/m1)*v2^2).
Kinetic energy = 1/2 mv^2

∙ 7y agoyes it is the same regardless of how much the object weighs

Does weight affect how far a catapult launches a tennis ball?
Yes. The force applied by the catapult will cause an acceleration on the tennis ball that is inversely proportional to the mass of the tennis ball.
What is the acceleration at highest pointn when ball is thrown straight up?
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
In throwing a ball upward discuss the velocity and acceleration when the ball returns to the thrower's hand?
A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.
Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
How does gravity affects a tennis ball dropped from a high diving board?
Gravity will result in the ball being accelerated downward at a rate of 9.8 m/s/s.
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.

A tennis player hits a 58.0 g tennis ball so that it goes straight up and reaches a maximum height of 6.17 How much work does gravity do on the ball on the way up?
Gravity is the same rate whether it is a tennis ball or a feather dropping. Gravity is 12.3 grams per cubic centimeter in a descending pattern and is a constant.
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
Why is the ball deccelerating on an inclined plane?
The acceleration due to gravity remains constant, regardless of incline. The fact that it is on an incline does not change the fact that it will remain constant, it will only change the component of that acceleration being applied to the ball.
In throwing a ball upward discuss the velocity and acceleration when the ball returns to the thrower's hand?
A the moment when the ball just touches the thrower's hand, it will have the velocity with which it was thrown and the acceleration will be equal to the acceleration due to gravity at the place acting vertically downwards.
What are the different forces acting on the ball while it’s in the air?
Gravity, force, and acceleration.
Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
How does gravity affects a tennis ball dropped from a high diving board?
Gravity will result in the ball being accelerated downward at a rate of 9.8 m/s/s.
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?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
If a ball is thrown vertically upwards and the acceleration on it is neg 9.8 due to gravity will the sign change when the ball changes direction to fall back down thus giving an acceleration of 9.8?
Yes. On the way up, negative acceleration is taking place because the ball is moving up and gravity is acting in the opposite direction. On the way back down, acceleration is positive, and the object starts at rest.
