Karten in diesem Stapel (9)
- 1The gravitational force between two point masses is directly proportional to......the product of the masses.
- 2The gravitational force between two point masses is inversely proportional to......the square of the distance between the masses.
- 3What type of object is affected by a gravitational force?Anything with mass.
- 4What is the range of a gravitational force?The force of gravity has infinite range
- 5State Newton's law of gravitation'The gravitational force between two masses is directly proportional to the product of the masses, and inversely proportional to the square of the distance between the centres of the masses'
- 6In this equation, for what does G stand?G is the 'universal gravitational constant'.
- 7What is the meaning of the negative sign in this equation?The negative sign indicates that the force is attractive.
- 8What is the effect on the gravitational force between two objects if the distance separating them is doubled?The new force is a quarter of the original value.
- 9What is the effect on the gravitational force between two objects if the masses of the two objects are halved?The new force is a quarter of the original value.
