Forces Flashcards
What is Friction?
Friction is a force that holds back the movement of a sliding object.
What is gravity
Gravity is a force which tries to pull two objects toward each other.
What is a Force?
Force is a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.
Name 8 things a force can do.
Push and pull, squeeze, press, attract to each other, change shape, motion, accelerate an object (speed up) and/or decelerate an object (slow down).
What does Force equal?
Force equals mass x acceleration.
Explain why you don’t fall through the floor.
Because the downward and upward forces balance each other out.
What is a fulcrum?
The ‘triangle shaped’ fulcrum is known as the triangle that balances out the lever for eg: on a seesaw, the fulcrum is the piece of (for example) metal that is on the bottom.
What is a Lever?
Eg: the long piece of (for example) metal that is used on a seesaw.
Explain what effort and load is.
Load is the (for example) weight of a rectangle that is on the edge of one side of a lever and effort is the other side where nothing is.
What is a Vector Diagram?
A vector Diagram is a Diagram used to show a (for example) experiment, so what the experiment was of.
What is buoyancy?
The ability or tendency of something to float in water or other fluid. It counts as contacted force (must physically touch to have an impact).
What is Friction?
The resistance that one surface or object encounters when moving over another. It counts as contacted force (must physically touch to have an impact).
What is drag?
Air resistance or water resistance. It counts as contacted force (must physically touch to have an impact).
What is electrostatic?
Electrostatic is relating to stationary electric charges or fields as opposed to electric currents. It counts as a non-contact force (not touching).
What is Nuclear?
Nnnnn
