![]() Hence, the acceleration due to gravity on the planet is half times the acceleration due to gravity on earth. The formula to calculate the acceleration due to gravity of the planet, Find the acceleration due to gravity on the planet? Solution: Problem 5: A planet has a radius and mass are half those of the earth. Speed is simply the: changeindistance speed (or velocity) - changeintime and is symbolized by: v d/t. Remember, the velocity, in this case, is just the speed of the particle at two different points. ![]() Hence, the values of g decreases by 4/9 times. The way you'll calculate this acceleration due to gravity is to first determine the velocity at two different points. The acceleration due to gravity at a height h is: Problem 4: What will be the decrease in the value of g as a body moves a distance of R/2 above the earth’s surface? Solution: Hence, the acceleration due to the gravity of the body is equal to 0.206 m/s 2. The acceleration due to gravity at the surface of Earth in terms of density is: Depth: When a body is put inside the earth’s surface the acceleration due to gravity becomes less.Ĭonsider an object of mass m inside the earth of mass M at depth D.Altitude: When a body moves away from the surface of the earth the force of attraction decreases as the distance between the earth and the body increases.While the force of gravitation is minimum at the equator of the earth approximately 9.78 m/s 2 as the radius of the earth is maximum at the equator ![]() The objectives of this experiment are as follows. The force of attraction is maximum at the pole of the earth approximately 9.82 m/s 2 as the radius of the earth is minimum at the pole. velocity of a falling object at set time intervals, and calculate the objects acceleration due to gravity. The expected results of this lab include: the acceleration due to gravity being 9.8m/s2, coefficient of kinetic friction being 0 due to the friction-less track, and the tension in the string being equal to the weight of the hanger. The Shape of Earth: As it is known that the shape of the earth is not spherical it’s quite oval so the gravitational force is different at different places. The acceleration of the hanger will then be measured using the Vernier motion detector.It is surprising that this value is larger than the accepted value. Here, substitute 6.67 × 10 -11 Nm 2 kg -2 for G, 6 × 10 24 kg for M and 6.4 × 10 6 m for r in the above expression to calculate g at the surface of Earth.įactor affecting acceleration due to gravity Measured acceleration due to gravity: 9.90 m/s2 Accepted value of acceleration due to gravity: 9.80 m/s2 Percent difference: 1.02 Conclusion: The measured value of the acceleration due to gravity was quite good only 1.02 larger than the accepted value of 9.80 m/s2.
