Physical Science I
The word that means the ability/capacity to cause motion.
What is Energy?
This is the unit used to measure Force.
What is newton(s)?
how does conduction vary from convection
The process where the nucleus of an atom splits into two or more smaller nuclei and other particles, releasing a large amount of energy
What is nuclear fission?
work/time
What is Power?
How does the unit for mass differ from the unit for weight?
mass is in kg
weight is in newtons
A wave where the movement of the particles is perpendicular (at a right angle) to the direction the wave travels
What is transverse wave?
What are 4 different types or Energy
What is Mechanical, Chemical, Electrical, Nuclear, Thermal, Radiant/Light and Sound?
The formula for Enery is measured with these units.
What is Joules or newton-meters?
A+ BC = AB + C
What is single replacement reaction?
The direction of a wave motion that longitudinal waves transfer energy?
What is parallel?
Holding a warm cup of cocoa will heat up your hand because they cause the particles in your hand to....
What is spead up/move around faster?
This is the formula for Gravitational Potential Energy
What is = m*g*h Kg x 9.81 x meters
hint: mass*gravity*height
These are the 2 multipliers in the formula for Work
What is force x distance (FxD)
This type of energy is transferred by convection currents?
What is thermal energy?
A car goes from being stopped at a light to increasing it's speed to 45m/s in 15 secs. Calculate its acceleration.
What is 3 m/s2 ?
The direction of heat between 2 objects travels in what direction?
What isthe direction of travel will be from the warmer object to the cooler object?
1/2*m*v2
What is the formula for Kinetic Energy?
With a rocket taking off what is the action reaction pair? Do action reaction pairs act on the same object?
rocket pushes gasses down, gasses push rocket up
To prove that work is being done on an object the object has to .....
move
Melting icecream is this type of change.
What is physical change?
