speed measurement are given in units of
measurements of acceleration are given in units of
how many centimeters are in a kilometer
It can be important to know about the velocity of an object , not just its speed, because
velocity also tells direction
Friction acts in a direction BLANK to the direction of an objects motion.
Unless an object at rest is acted upon by another force, it stays at rest due to its
an BLANK can cause an objects motion to change
The amount of matter in an object is called
Newtons second law of motion states the relationship of mass ,acceleration,and force. it says that
force equals acceleration divided by mass
An BLANK causes objects to move in a circle
The unit of force, a newton, is equal to
kj x m/s
An object in free fall BLANK until it reaches terminal velocity
Potential energy is energy
that is stored
Kinetic energy depends on
mass and velocity
The suns energy comes from
Sunlight is a form of
An electric blanket transform electric energy to
The formula wieght x height is used to calculate
elastic potential energy
The energy stored in the nucleus of an atom is called
The distance anobject travels per unit of time
The steepness of a line on the graph
The rate at which velocity changes
speed given in a direction
The basic SI unit of length
A place or object used ofr comparison to determine in an object is in motion
The speed of an object at one instant of time
A system of measurement based on multiples of ten and on established measures of mass,length, and time
Internation system of units
The overall rate at which an object moves ; calculated by dividing the total distance an object travelsby the total time .
The force that one surface exerts on another when two surfaces rub against eachother
The force that pulls objects toward each other
A push or pull exerted on an object
A fluid friction experienced by objects falling through the air
The greatest velocity a falling object can acheive.
Friction that acts on objects that are not moving
Forces that produce a nonzero net force , which changes an object's motion .
A unit of measure that equals the force required to accelerate1 kilogram of mass at 1 meter per second
The rule that in the absence of outside forces the total momentum of objects that interact does not change.
Law of conversation
An object that is trown
The overall force on an object when all the idividual forces acting on it are added together.
Friction that occurs as an object moves through a fluid
The amount of matter in an object
Friction that occurs when one solid surface slides over another
The product of an objects mass and velocity
The force of gravity on an object at the surface of the planet
Equal forces acting on an object in opposite directions
The ability to do work or cause change
The potential energy stored in chemical bonds
The energy of stretched or compressed objects
elastic potential energy
The total potential and kinetic energy of the particles in an object
Energy that an object has due to its motion
The energy of light and other forms of radiation
The potential energy stored in a nucleus of an atom
Kinetic or potential energy asssociated with the motion or position of an object.
potential energy that depends on the height of an object
gravitational potential energy
Stored energy thata results from the position or shape of an object.
