Does the height of a ball affect how much it bounces?
Yes, the height from which a ball is dropped affects how high it bounces back. The higher the drop height, the higher the bounce due to the increased potential energy the ball gains from the greater height.
How much potential energy does a ball have when it reaches the top of its ascent being 1kg with a velocity of 30msec?
The potential energy of an object at a particular height is given by the formula: Potential Energy = mass x gravity x height. At the top of its ascent, the ball's height is maximum, meaning all of its initial kinetic energy has been converted to potential energy. Therefore, the potential energy of the ball at the top of its ascent is 0.
A student throws the same ball straight upwards to a height of 7.50 m how much work did the student do?
The work done by the student to throw the ball upwards is equal to the potential energy gained by the ball at the maximum height. The work done is given by the formula: work = force * distance. In this case, the student exerted a force to lift the ball against gravity to a height of 7.50 m, so the work done is equal to the potential energy gained by the ball, which is mgh, where m is the mass of the ball, g is the acceleration due to gravity, and h is the height.
How much potential energy does 60 kg skater have at 12 meters above ground?
The potential energy of the skater at 12 meters above the ground can be calculated using the formula: Potential energy = mass * acceleration due to gravity * height. Given that the mass is 60 kg, acceleration due to gravity is 9.81 m/s^2, and the height is 12 meters, the potential energy would be approximately 7,058.4 Joules.
How much energy (in Joules) does a 3-kg vase possess when it's placed on shelf 2.5 meters above the ground?
The potential energy of the 3-kg vase can be calculated using the formula: potential energy = mass * gravity * height. With a mass of 3 kg, gravity as 9.81 m/s^2, and a height of 2.5 meters, the potential energy would be approximately 73.58 Joules.

If the height is 246000000 then how is the potential energy?
246... of what? To calculate the potential energy, multiply mass x gravity x height. In SI units, use kg for mass, 9.8 for gravity, meters for height. Answer will be in Joule.If the height is in meters, the acceleration of gravity is much, much less. So you'll have to calculate the acceleration yourself by g = G × Mearth/246,000,0002.

A ball thrown upward reaches a height of 13 meters how much time did it take to get this high?
Assuming the ball is thrown vertically upwards with no air resistance, the time it takes for the ball to reach a certain height can be calculated using the kinematic equation: ( h = v_i t - \frac{1}{2} g t^2 ), where ( h = 13 ) meters (maximum height), ( v_i = 0 ) (initial velocity), and ( g = 9.81 , \text{m/s}^2 ) (acceleration due to gravity). Solving for ( t ) gives approximately 1.46 seconds.
How does the drop height of a ball affect the height of its bounce?
The higher the height at which the ball is dropped from, the higher the ball bounces. Look at it in terms of energy. Initially, before the ball is dropped, the ball's potential energy, E is given by E = mgh, where m is the mass of the ball, g is the gravitational acceleration and h is the height of the ball. When the ball is dropped, the potential energy is converted to kinetic energy, and at the point of impact, , i.e. when the ball is level with the ground, and h = 0, the kinetic energy is E, given by E = 0.5mv2, where v is the velocity of the ball. The ball hits the ground, and rises again - its kinetic energy is being converted back to potential energy. The ground absorbs some of the energy upon impact, but most of the energy stays with the ball. So the kinetic energy is converted to potential energy, and once all of the kinetic energy is converted, the ball reaches its maximum height. Clearly, a higher kinetic energy corresponds to a higher bounce height. 0.5mv2 = mgh The amount of energy that the ground absorbs does not change much with the height of the ball as well.As the drop-height increases, the bounce-height too will increase, but not always in direct proportion. The efficiency will decrease as the drop height is increased.
What has more energy a Snickers bar or a bowling ball held two meters off the ground?
A Snickers bar contains around 250 calories of energy, which is approximately 1,046 kilojoules. In contrast, a bowling ball held two meters off the ground possesses gravitational potential energy calculated using the formula (PE = mgh), where (m) is the mass of the bowling ball, (g) is the acceleration due to gravity (approximately 9.81 m/s²), and (h) is the height (2 meters). Depending on the weight of the bowling ball, it can have significantly more energy than the Snickers bar when lifted. For example, a typical bowling ball weighing around 7 kg has a potential energy of about 137.2 joules, which is much less than the energy of the Snickers bar.

1-kg brick is lifted to a height of 30 meters and then dropped How much potential energy remains after 2 seconds of freefall?
Use one of the formulas for constant acceleration to calculate how many meters the brick will fall after 2 seconds. Subtract this from the 30 meters, to see how high the brick is above ground. Finally, use the formula for potential energy: PE = mgh, to calculate the potential energy.
