Front

What factors affect the period of a pendulum?

Back

The period of a pendulum is affected by the length of the pendulum and the acceleration due to gravity, which varies depending on the planet.

Front

What does the friction force depend on?

Back

The friction force depends on the normal force acting on the object and the nature of the contact surface. It does not depend on the speed of the object.

Front

What happens to the number of waves per second if a wave has a greater frequency?

Back

If a wave has a greater frequency, the number of waves per second increases.

Front

How do you calculate the change in momentum?

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position.

Front

What is the relationship between frequency and wavelength in waves?

Back

Front

What is the principle of conservation of momentum?

Back

The principle states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is the effect of mass on gravitational force?

Back

The gravitational force between two objects increases with the mass of the objects and decreases with the square of the distance between them, as described by Newton's law of universal gravitation.
