Given Radius is 4.76*10^5 m
Astronaut drops a hammer of 0.85kg from a height of 1.25m. It takes 3s to reach the ground
What is the gravitational field strength?
Homework Equations
The Attempt at a Solution
g=a=Δv/t
v=d/t
v=1.25/3
a=1.25/3/3
But that's not the answer
Gravitational field strength is calculated by dividing the force of gravity acting on an object by the mass of the object. This can be represented by the equation g = F/m, where g is the gravitational field strength, F is the force of gravity, and m is the mass of the object.
The SI unit for gravitational field strength is Newtons per kilogram (N/kg). However, it can also be measured in other units such as meters per second squared (m/s²) or multiples of the Earth's gravitational field strength (g).
The gravitational field strength between two objects is inversely proportional to the square of the distance between them. This means that as the distance between two objects increases, the gravitational field strength decreases.
Yes, gravitational field strength can vary on different planets depending on their mass and radius. The larger the mass and smaller the radius of a planet, the stronger its gravitational field strength will be.
Gravitational field strength is directly related to gravitational potential energy. An increase in gravitational field strength will result in an increase in gravitational potential energy, while a decrease in gravitational field strength will result in a decrease in gravitational potential energy.
