Q:

What is force and motion?

A:

Quick Answer

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:

    What are some force and motion experiments?

    A:

    Some force and motion experiments include dropping two objects of different masses from the same height to demonstrate Newton’s law of acceleration, and the terminal velocity experiment to demonstrate the interaction of the effect of drag or resistance on acceleration. Two objects with different masses dropped from the same height reach the ground at the same time.

  • Q:

    What is the law of acceleration?

    A:

    The law of acceleration is formally referred to as Newton's Second Law of Motion and defines the rate of acceleration as a product of the force exerted on the object and the mass of the object. The rate of acceleration increases as the net force increases. The inverse is true for mass, with the acceleration decreasing as the mass increases.

  • Q:

    What is the formula to calculate force?

    A:

    For an object with unchanging mass, force equals mass times acceleration. This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.

  • Q:

    What are the positives and negatives of g-force?

    A:

    G-force is an attractive force caused by the acceleration due to gravity on one object by another object. Positive g-force increases the apparent weight of a body while negative g-force decreases the apparent weight of a body.
