Question | Answer |
---|---|
Beaker | Holds liquids |
Triple Beam Balance | Measures the mass of an object |
Apron | Protects clothes |
Microscope | Magnifies microscopic objects |
Ruler | Measures the length of objects |
Atom | Smallest particle in which an element can be divided & still maintain properties of that element |
Nucleus | Center of an atom that is made of protons and neutrons |
Proton | Positively charged particles located in the nucleus of the atom |
Neutron | Have no electric charge |
Electron | Negatively charged particles found outside of an atom |
Speed | Distance traveled by an object in a given amount of time |
Velocity | Objects speed & direction at a given distance |
Acceleration | Change in an objects speed or direction over time |
Force | Push or pull |
Balanced force | Occurs when the total of forces on an object equals 0 and the objects motion does not change |
Unbalanced force | When the net force of an object does not equal 0 and the object moves |
Direction | Where an object is going |
Newton's 1st Law | An object will keep doing whatever it is doing unless the forces acting on it become unbalanced |
Newton's 3rd Law | All forces act in pairs |
Newton's 2nd Law | The smaller the mass of an object the greater its accelertation when a certain force is applied to the object. |
