In summary, the conversation discussed how to calculate the acceleration of a ball dropping from a height of 3 meters in 67 milliseconds, with given weight, time, and height. The equation used was d=(0.5)gt^2, where d is distance, t is time, and g is the acceleration due to gravity (approximately 9.81 m/s^2). However, it was noted that the measurement of time may have been incorrect and should be repeated for more accurate results.

t=time

g= acceleration due to gravity

and I'm sure you know that mass doesn't matter

d = (0.5)gt^2

g = 9.8

t = 0.67

Therefore,

0.5 x 9.8 x 0.67 x 0.67 should equate to 3 - or am I mistaken and/or made some errors?

67ms = 0.067s not 0.67nobodyuknow said:

0.5 x 9.8 x 0.67 x 0.67 should equate to 3 - or am I mistaken and/or made some errors?

And how did you measure the time? You should repeat the experiment several times and see how big is the error.

Gravitational acceleration is a measure of the acceleration of an object towards the center of a massive body due to the force of gravity. It is commonly denoted by the symbol "g" and has a constant value of approximately 9.8 meters per second squared on Earth.

Gravitational acceleration can be calculated using the equation g = G * M / r^2, where G is the gravitational constant, M is the mass of the massive body, and r is the distance between the object and the center of the massive body.

The gravitational constant, denoted by the symbol G, is a fundamental constant in physics that is used to calculate the force of gravity between two objects. Its value is approximately 6.674 x 10^-11 m^3 kg^-1 s^-2.

Yes, gravitational acceleration can vary between different planets due to differences in their mass and radius. For example, the gravitational acceleration on Mars is approximately 3.7 meters per second squared, while on Jupiter it is approximately 24.8 meters per second squared.

Yes, gravitational acceleration can change depending on the location and mass of the objects involved. For example, if an object is moved closer or further away from a massive body, the gravitational acceleration will change. Additionally, the gravitational acceleration can also change if the mass of the massive body changes.
