Motion And Forces
Forces
Force and mass determine accerleration
Newtons second law relates force, mass, and acceleration
Newton's second law
Force equals mass times acceleration
Mass and acceleration
Forces change motion
A force is a force or pull
Types of forces
Size and direction of forces
balanced and unbalenced forces
FOrces of moving objects
Newton's first law relates force and motion
Galileo's thought experiment
Newton's first law
Inertia
Forces act in pairs
Newton's third law relates
action and reaction forces
Action an d reaction pairs
Action and reaction versus
balanced forces
Forces transfer momentum
Forces can change direction of motion
Centripetal force
Circular motion and newton's second law
Newton's three laws describe and protect motion
Objects in motion have momentum
momentum can be transferred from one object to another
two types of collisions
momentum and newton's third law
Machines
Machines help people do work
Six simple machines have many uses
there are six simple machines
lever
wheel and axle
pulley
inclined plane
wedge
screw
the mechancile advantage of a machine can be calculated
Modern technology uses compound machines
compound machines are combinations of simple machines
gears
mechanical advantage of compound machines
modern technology creates new uses for machines
microtechnology and nanotechnology
machines change the way force is applied
changing size and distance
changing direction
mechanical advantage of a machine
work transfers energy
energy
work
output work is always less than imput work
efficiency and energy
increasing efficiency
Work and Energy
Work is the use of force to move an object
Energy is transferred when work is done
work transfers energy
work changes potential and kinetic energy
calculating gravitational potential energy
calculating kinetic energy
calculating mechanical energy
the total amount of energy is constant
conserving mechanical energy
losing mechanical energy
forms of energy
Power is a rate at which work is done
Power can be calculated from work and time
calculating power from work
horse power
Power can be calculated from energy and time
calculating power from energy
everyday power
force is necessary to do work
force, motion, and work
calculating work
objects that are moving can do work
Gravity, Friction, and pressure
Gravity is a force exerted by masses
Masses attract eachother
the force of gravity
Gravity of earth
weight and mass
Gravity keeps objects in orbit
Spacecraft in orbit
People in Orbit
Friction is a force that opposes motion
Friction occurs when surfaces slide against eachother
Forces and surfaces
friction and heat
motion through fluids produces friction
Pressure depends on force and area
Pressure describes how a force is spread over an area
Pressure acts in all directions in fluids
pressure in fluids depends on depth
Pressure in air
Pressure in water
Fluids can exert a force on objects
Fluids can exert an upward force on objects
buoyancy
Density and buoyabcy
The motion of a fluid affects it's pressure
Bernoulli's principle
Applying bernoulli's priinciple
forces can be transmitted through fluids
Pascal's principle
Hydraulics
Motion
An object in motion changes position
Position describes the location of an object
Describing a position
measuring distance
Motion is a change in posistion
Describing Motion
Relative Motion
Acceleration measures how fast velocity changes
calculating acceleration
Speed and direction can change with time
acceleration over time
velocity time graphs
Acceleration can be calculated from velocity and time
Speed measures how fast position changes
Calculating Speed
Position can change at different rates
Average speed
distance time graphs
velocity includes speed and direction
Velocity Versus speed
