Q:

What is force and motion?

A:

Force is any influence to an object which changes its motion, while motion itself is the change in position of an object in relation to is speed, location and acceleration. There cannot be movement without force used against an object to set it in motion.

A bicycles tires move because the person riding it exerts force on the pedals, which in turn moves the chain and the tires. This force causes the bike to be in motion. If there is no force being exerted on an object, then the object is said to be at rest and have a constant position. An object's motion cannot change unless force is acted upon it as stated by Newton's First Law.

  • Q:

    How are force and mass related?

    A:

    Force and mass are related by their opposite influence on acceleration: Force increases acceleration, whereas mass causes acceleration to decrease. Mass is a measure of resistance to acceleration and force is an interaction that causes acceleration, according to The Physics Hypertextbook. Both represent scientific entities acting on the rate of change in velocity of an object, defined as acceleration.

  • Q:

    What does the law of inertia apply to?

    A:

    The law of inertia is a fundamental physics principle used to describe how an object behaves in motion or at rest, particularly when forces are applied to it. The object can be anything that has mass.

  • Q:

    What is the path taken by a flying object?

    A:

    The path taken by a flying object in motion on the surface of the Earth is called a parabola. A parabola is a symmetrical arc, and the trajectory of flying objects with negligible air resistance in a gravitational field, as on the surface of the Earth, follows this path.

  • Q:

    What is the law of inertia?

    A:

    The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.
