6. Circular motion and gravitation Flashcards
1
Q
Period =
A
the time taken for the object to go round the circle once.
2
Q
Frequency =
A
the number of times the object goes around the circle each second.
3
Q
Angular displacement =
A
the angle moved around the circle by an object form where its circular motion starts.
4
Q
Angular velocity =
A
angular displacement/ time for displacement to happen.
5
Q
Newton’s law of gravitation =
A
the force of attraction between two objects is proportional to the product of the masses and inversely proportional to the square of their separation.
6
Q
Gravitational field strength =
A
the force per unit mass experienced by a small point mass placed at that point.
