# Does acceleration due to gravity depend on the size of the ball?

No, each molecule in the ball is being pulled to Earth at the same speed, so why should it matter how many molecules are grouped together, they will all be falling at the same speed. Try it, drop two objects of different sizes, and unless there is a large difference in air resistance between the two, they will hit the ground at approx. the same time.

### If a ball is thrown straight up whats its acceleration at the top of its path?

An object moving under the influence of gravity only and no other outside forces has a constant acceleration of 9.8 meters (32.2 feet) per second2, directed down. That's the acceleration of the ball, from the moment it leaves your hand until the moment it hits something, regardless of what direction you throw it. The speed changes. The acceleration doesn't, regardless of the angle, speed, trajectory, color, temperature, cost, size, mass, political affiliation, or weight of…

### Earth had twice the present mass. Assume the properties stay the same. What would the acceleration of the more massive Earth due to the Sun compared to the present acceleration of earth from the Sun?

The acceleration of one mass toward another one on account of gravity doesn't depend on the mass of the smaller one. That's why all objects fall to earth with the same acceleration. The size of an object's orbit around a large mass doesn't depend on the smaller object's mass either. That's why a space-walking astronaut and the Space Shuttle that his pajamas are stored in for later can stay in the same orbit without flying…

### In throwing a ball upward discuss the velocity and acceleration when the ball reaches its maximum height?

If a ball, or any object, is thrown vertically it will always be accelerating downwards at a rate of 9.8 m/sec2 until it hits something. Because it starts with an upward velocity, this acceleration slows it down until it has zero. This is obviously the point of maximum height. After this it will start downwards always with the same acceleration. After a second from its maximum height, it will have a velocity of 9.8 m/sec…

### An object that is thrown vertically upward will return to its original position with the same speed as it had initially if air resistance is negligible if air resistance is appreciable?

As an object rises WITH air resistance, the acceleration is larger in size than g, because both gravity and air resistance will be causing a downward acceleration. As the object FALLS with air resistance, the acceleration will be smaller in size than g, because gravity and resistance will be opposing each other. Because of the smaller acceleration being applied over the same distance, the return speed will be slower than the launch speed.

### What will be the acceleration due to gravity or its surface when earth contracts half of its present size without change its mass?

The current acceleration due to gravity is 32 feet per second per second, or 9.8 meters per second per second. The "inverse square" equations for gravity and distance indicate that if the mass remains constant while the radius is cut in half, the force of gravity would increase by a factor of four. So the new acceleration due to gravity would be 128 feet per second per second, or 39.2 meters per second per second.

### What is the ball size for an outdoor soccer game?

The size of a soccer ball does not depend on whether the game is played indoors or outdoors. In fact, it depends on how old the players are. If the player is approx. 4-8 years old they use a size 3, if they are approx. 8-12 years old they use a size 4, and if the player is 12+ they use a size 5, an adult size ball.

### What are some real life examples of Newton's second law of motion?

The second law of motion states that the acceleration of the an object depends on the mass of the object and the size of the force acting on it a good example is bowling because the acceleration of the bowling ball hitting the pins are hitting the shape and the size of it. And the force acting on it is the bowling ball and bowling pin that is an example of the second law of…

### How come all bodies sliding down a frictionless inclined plane have same acceleration?

all bodies have same acceleration while coming down from an inclined plane because in such type of case acceleration does not depends upon mass....acceleration can be given as a=gsinÎ¸......Î¸(theta) is the angle of the inclined plane. g is the acceleration due to gravity or 9.81 m/s2. *Note: the acceleration due to gravity is actually based on the mass of both bodies and the square of the distance between their centers. While this means that gravity…

### What is the magnitude of gravity the earth exerts on a man with a mass of 80.0kg?

Here we have to be precise with the terms that we use. Gravity is the property of an massive body. Gravitational force is the force between two massive bodies. Acceleration due to gravity is the acceleration produced in a body due to gravitational pull on it. And it is constant at a particular. place and independent of the size , mass and nature of the body. If M is the mass then Mg is the…

### Does Jupiter have stronger gravity than Earth?

Larger masses exert stronger gravitational forces, so gravity on Jupiter is much stronger than that of Earths. Due to Jupiter's larger size (its the largest planet in our solar system) jupiter has more gravity. It has about 2.5 times the gravity of earth therefore the acceleration due to gravity is 26 m/s/s.

### What would happen to your weight if the Earth's mass doubled without changing its size?

From the Law of Gravity, F=(GmM)/rr where M is the mass of Earth and m the human mass, G=6.67*10^(-11) r is Earth's radius The force F is F=mg also mg=weight where g is the acceleration due to gravity and m the human mass Putting them together, we get that the acceleration due to gravity g, is g=GM/rr From this, we get that if the mass of the Earth was doubled, then the acceleration due to…

### How does an object affect its accelration during free fall?

Without propellers, jets, or a parachute, an object can't to anything to affect its acceleration when it's falling. "Free fall" means moving under the influence of gravity only, with not even any air resistance. In that situation, on or near the surface of the Earth, acceleration is constant, regardless of the size, shape, mass, weight, or gender of the falling object. That number is 9.8 meters (32.2 feet) per second2 ... known as the acceleration…

### Why does the rubber ball hits the ground before the foam ball?

Two things affect the balls while falling - Gravity and Air Resistance. Gravity affects both balls equally. Air resistance exerts a similar force on objects of the same size and shape. A Foam ball weighs less so the same amount of air resistance causes a larger slowing effect on a light foam ball than it does on a heavy rubber ball.

### Do heavy objects fall faster?

They don't fall faster. Weight has nothing to do with how fast things fall. Gravity is a constant and all things fall at the same speed due to gravity. A cannon ball drop from a high building would hit the ground at the same time as a soccer ball dropped from the same height at the same time. The only thing that makes one faster or slower is wind resistance (aerodynamics). If you take a…
