Term | Definition |
What is an ion? | An atom which loses or gains electrons |
What happens during ionic bonding? | The electrons are transferred |
What is the formula of acceleration? | acceleration= change in velocity/ time taken |
What is the formula of distance traveled? | distance traveled= average speed (times) time |
What is the formula for momentum? | momentum= mass (times) velocity |
what is the formula for kinetic energy? | kinetic energy= mass (times) 1/2 (times) speed2 |
What are the 3 components of an atom? | 1) Protons 3) Neutrons 2) Electrons |
What are atoms features? | An atom is a tiny particle/molecule which contains protons, electrons and neutrons. |
What are isotopes? | Atoms with the same atomic number(same number of protons and electrons) but different mass numbers.(two atoms with the same number of protons but differnt number of neutrons.) |
What is the formula of efficiency? | Efficiency= useful energy transferred by the device/ total energy supplied to the device. |
What is the formula of force? | force= mass (times) acceleration |
What is the difference between mas and weight? | Mass is a measure of how much stuff is in an object(KG). Weight is a force acting on that stuff(N). |
What is the formula of density? | density= mass/ volume |

What is the formula of magnification? | magnification= objective lens (time) eye piece lens |
What is the formula of actual size? | actual size= measured size/ magnification |
What are Prokaryotic cells? | these cells don't have any nucleus and this is a bacterial cell because they have a single- celled organism |
What are Eukaryotic cells | these cells have a nucleus and is found in plants and animal cells |
