Physics in Daily Life
This branch of science deals with matter, energy, motion, and forces.
Physics
This is the rate of change of velocity with respect to time.
Acceleration
This is a substance that can flow and take the shape of its container; it includes liquids and gases.
Fluid
This is the continuous flow of electric charge through a conductor.
Electric current
This machine combines two or more simple machines to perform a task.
Compound machines
This is the ability to do work or cause change.
Energy
This scientist formulated the three laws of motion that explain how forces affect the movement of objects.
Isaac Newton
This principle explains why pressure applied to an enclosed fluid is transmitted throughout the fluid.
Pascal's Principle
What form of energy powers lights, fans, and many household appliances?
Electrical Energy
This simple machine consists of a grooved wheel and a rope or cable and can change the direction of an applied force.
Pulley
This is a push or pull that can change an object's motion or shape.
Force
This is the change in position from the initial point to the final point, including direction.
Displacement
In Pascal's Principle formula, what does A represent?
Area
What are the two primary types of circuits?
Series and Parallel Circuits
This simple machine consists of a sloping surface used to raise or lower objects with less effort.
Inclined plane
This is the rate at which work is done or energy is transferred.
Power
This is the tendency of an object to resist changes in its state of motion.
Inertia
This is the SI unit of pressure, equivalent to one newton per square meter.
Pascal
This law is expressed as V=IR, relating voltage, current, and resistance in an electrical circuit.
Ohm’s law
Give an example of a lever, which is a simple machine consisting of a rigid bar that rotates around a fixed point called a fulcrum.
Scissor
Using the formula W=Fd, what physical quantity is calculated when a force moves an object through a distance in the direction of the force?
Work
This principle states that every action force has an equal and opposite reaction force.
Newton's Third Law of Motion
Using the formula P=F/A, what physical quantity is calculated by dividing the applied force by the area?
Pressure
A circuit has a voltage of 12 V and a resistance of 4 Ω. Using I=V/R, what is the current?
3 A
A machine lifts a 200 N load using a 50 N effort. Using MA= Effort/Load, what is its mechanical advantage?
