What are the first 3 laws of Newton about?

• Motion

• Magnitude

• Propellants

• Expulsion

Which law of Newton refers to 'Net force' which is required to propel a craft forward.

• Rest

• Acceleration

• Inertia

• Mass

In ancient Greek, the word 'thermo' refers to?

• heat or warmth

• earth or soil

• water or liquid

• air or wind

What does Newtons first law of motion state?

• Object always move in the direction of the applied force

• An object at rest will remain at rest unless acted upon by an external force.

• All objects in motion eventually come to a stop due to friction

• Object in motion will continue to accelerate indefinitely

What is the primary function of an electrical conductor?

• absorbs light energy

• generates magnetic fields

• transmits electric current

• convert sound waves into electricity

What does the term 'viscosity' refer to

• resistance to flow in fluids

• ability to conduct electricity

• measure of temperature change in solids

• the density of gases

In technical terminology, which words is a synonym for 'motion'?

• Density

• Refraction

• Kinematics

• Acceleration

What does the term 'SI system of units' refer to?

• a method of catergorising animals & plants

• International standard for measurement used in science worldwide

• a system for classifying rocks & minerals

• An ancient system for measuring time

Why is using 'design method' important in engineering?

• creates unnecessary paperwork

• reduces creative thinking

• slow down project completion

• Helps make better, more innovative solutions

What is a 'prototype' in terms of engineering design?

• a digital simulation for marketing purpose

• a theoretical concept without practical application

• a preliminary model used for testing & evaluation

• the final product for mass production
