FORCE AND MOTION

Question 1

F = M X A:

Answer 1

FORCE (N)= MASS (KG) X ACCELERATION (M/S) SQUARED

Question 2

W = M X G:

Answer 2

WEIGHT (N) = MASS (KG) X GRAVITATIONAL FIELD STRENGTH (G)

Question 3

F = K X E:

Answer 3

FORCE (N) = SPRING CONSTANT (N/M) X EXTENSION (M)

Question 4

FORCE:

Answer 4

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. (N)

Question 5

MASS:

Answer 5

Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied. (KG)

Question 6

ACCELERATION:

Answer 6

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing. (M/S) SQUARED

Question 7

GRAVITATIONAL CONSTANT:

Answer 7

The gravitational constant is the proportionality constant that is used in the Newton’s Law of Gravitation. … The value of the gravitational constant is the same throughout the universe. The value of G is different from g, which denotes the acceleration due to gravity. (G)

Question 8

SPRING CONSTANT:

Answer 8

k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position. The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constants. (K)

Question 9

EXTENSION:

Answer 9

An extension is the act of getting more time, space, or length, like an extension of a deadline that gives you one more day to turn in a paper, or extensions that make your hair look longer. (E)
