Question 1

Inclined Plane

Answer 1

A platform the is angled at an acute angle to the horizontal

Question 2

mass

Answer 2

The amount of a particular object measured in Kg or g

Question 3

Weight

Answer 3

The mass of an object multiplied by the force of gravity (9.8m/s2) and measured in N

Question 4

Normal Force

Answer 4

The equal and opposite force created by the ground or touching surface opposing gravity which keeps objects from falling through the earth

Question 5

Acceleration

Answer 5

The increase of velocity per second

Question 6

Force Parallel

Answer 6

If an object sits upon an inclined plane, the force that pushes the along the plane is the parallel force
- It is calculated as F=mgsin(theta)
- to look at it in a geometrical and engineering sense the weight can be split into two components: parallel and perpendicular, the Parallel is the sine aspect and the perpendicular is the cosine aspect

Question 7

Force Perpendicular

Answer 7

The opposite of the normal force which the aspect of the gravitational force which pushes into the plane at a perpendicular angle
- Calculated as F=mgcos(theta)
- If a line is drawn to connect the end of the two forces to create a right angle, the hypotenuse is the weight or the total F=mg

Question 8

Newton’s second law

Answer 8

F=mg
