Question

Какая сила тяжести действует на мяч с массой 450 г

Answer 1

F = (m * g) = 0,45 * 10 = 4,5H.

Answer 2

Calculating the Force of Gravity on a 450g Ball

The force of gravity acting on an object can be calculated using the formula:

F = m * g

Where: - F is the force of gravity - m is the mass of the object - g is the acceleration due to gravity

Mass and Acceleration Due to Gravity

The mass of the ball is given as 450g. To calculate the force of gravity, we need to convert the mass to kilograms, as the standard unit for mass in physics is kilograms.

1 kilogram (kg) = 1000 grams (g)

So, the mass of the ball in kilograms is: m = 450g = 450/1000 kg = 0.45 kg

The acceleration due to gravity, denoted as g, is approximately 9.81 m/s^2 on the surface of the Earth.

Calculating the Force of Gravity

Using the formula F = m * g, we can calculate the force of gravity acting on the ball:

F = 0.45 kg * 9.81 m/s^2 = 4.425 N

Therefore, the force of gravity acting on the 450g ball is approximately 4.425 Newtons.
