Q:

What are the four main types of motion?

A:

The four main types of motion are translational, oscillatory, reciprocating and rotational motion. Some mechanisms use one type of motion for input but another type entirely for output.

Motion is one of the most popular topics in physics, describing everything from the tiniest movement to something as large as the rotation of the a planet.

Over the centuries, scientists have discovered numerous laws that help us understand motion and the factors that cause changes in movement. Motion is driven by force, which is what gets things moving or changes the motion. Physicists use several criteria to measure motion. The speed at which an object moves, for example, is called velocity.

    What does momentum mean?

    A:

    In physics, "momentum" is a property that describes an object's motion. Linear momentum, the momentum of an object moving in a straight line, is the mass of the object multiplied by its velocity.

    Who discovered retrograde motion?

    A:

    Retrograde motion was first described by Ptolemy as part of his solar system model. He described the motion of the planets in relation to the stars using the terms "retrograde" for westward motion and "prograde" for eastward motion.

  • Q:

    What is "rotational motion"?

    A:

    Rotational motion is motion around an object's center of mass where every point in the body moves in a circle around the axis of rotation. The center of mass is the point in an object from which there is an equal amount of mass in any two opposite directions. The axis of rotation is a line that passes through the center of mass.

  • Q:

    How is friction unhelpful?

    A:

    Friction is a force that opposes motion, so it is unhelpful in all situations where the motion of an object is desired. A by-product of friction is that energy is wasted in the form of heat, which can cause problems in temperature-sensitive environments.
