Gravitational Field

An invisible region surrounding an object where every other object will experience an attractive force due to the object's mass.

Simple Harmonic Motion (SHM)

The periodic back-and-forth motion of an object displaced from equilibrium, where the restoring force is proportional to the displacement.

Amplitude of a Wave

The maximum displacement of a wave from its resting position.

Newton's Law of Universal Gravitation (Distance and Force)

The force of gravity between two objects is inversely proportional to the square of the distance between their centers of mass.

Study Notes

Gravity and Motion

  • The concept of gravitational field describes an imaginary region of space around an object where every other object experiences an attractive force.

Types of Motion

  • Simple harmonic motion is experienced by an object displaced by a force from an equilibrium position.

Waves

  • The maximum displacement a wave can move from its resting position is known as amplitude.

Newton's Law of Universal Gravitation

  • If the distance between two objects is doubled, the gravitational force between them is quartered.

Gravitational Potential Energy

  • An object has the greatest gravitational potential energy (GPE) at its highest point in a gravitational field.

Types of Mechanical Waves

  • Transverse waves occur when the particles are displaced perpendicular to the direction the wave travels.
  • Longitudinal waves occur when the particles are displaced parallel to the direction the wave travels.

Acceleration

  • Rotational acceleration involves a change in the rate of rotation or the direction of the axis.

Moment of Inertia

  • The sum of the product of the mass of every particle with its square of the distance from the axis of rotation is called the moment of inertia.

Gravitational Field Strength

  • If two objects are brought closer to each other, their gravitational field strength increases.
