Physics 1: Introduction to Mechanics

Question 1

Force

Answer 1

a physical quantity that pushes, pulls, or twists an object

Question 2

Friction

Answer 2

is a force that opposes motion and is present whenever two surfaces rub over each other

Question 3

Drag

Answer 3

a Force acting opposite to the motion of any object moving in or through a surrounding Fluid.

Question 4

Mass

Answer 4

the amount of matter in an object; a measure of the objects resistance to motion. It is measured in kilograms (kg)

Question 5

Weight

Answer 5

the force of gravity acting on a mass. It is measured in newtons (N).

Question 6

Gravity

Answer 6

fundamental force of attraction that objects with mass have for each other.

Question 7

How are forces Measured

Answer 7

Forces are measured in Newtons (N),

Question 8

The Relationship between Force, Mass and Weight: Calculations

Answer 8

F = ma

Force = Mass x Acceleration

Question 9

The Relationship between Mass, Weight and Gravity

Answer 9

W = mg

Weight = Mass x Gravity

Question 10

Velocity, Distance and Time

Answer 10

V = d/t

Velocity ( speed ) = Distance / Time
