Force And Motion

Question 1

Force

Answer 1

Strength or energy as an attribute of physical action or movement

Question 2

Mass

Answer 2

Mass is just the amount of matter (stuff) in an object

Question 3

Acceleration

Answer 3

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time

Question 4

Gravitational Constant

Answer 4

Newtons Law

Question 5

Spring Constant

Answer 5

Spring Constant is a measure of the stiffness of a spring up to its limit of proportionality or elastic limit - Hooke’s Law

Question 6

Extension

Answer 6

Hooke’s Law: force exerted by a spring = extension × spring constant. This is when: force is measured in newtons (N)

Question 7

F = m x a

Answer 7

F = Force

M = Mass

A = Accelaration

Question 8

W = m x g

Answer 8

W = Weight

M = Mass

G = Gravitional Field Strength

Question 9

Scalar

Answer 9

A quantity that has magnitude but no particular direction is described as scalar

Question 10

Vector

Answer 10

A quantity that has magnitude and acts in a particular direction is described as vector
