semester A examination
|the rate at which velocity is changing. (includes direction)
|a= change in V / change in T
|diminishes net forces acting on an object.
|when objects come together and bounce off of each other
|when to objects interact and stay attached to each other after the collision.
|the projection of a vector quantity, as force or velocity, along an axis.
|the part of data that can be changed in an experiment
|the place where an object is going.
|includes direction the change in position of an object
|the equation for displacement
|x final -x intial
|the space between two places or object.
|units for distance
|how long something lasts
|referring to an oval shaped curve that is the path of a point that moves such that the sum of its distances from two fixed points is contant
|the property of an object of system that enables to do work
|unit for evergy
|an influence that accelerates an object using a push or a pull, also a vector quantity
|units for force
|motion under the influence of the gravitational force only
|the force that acts to resists the relative motion (or attempted motion) of objects or materials that are in contact
|gravitational field force
|a force field that exists in the space around every mass or group of masses.
|left to right, right to left
|an educated guess before an experiemt
|product of force and time interval during which the force acts.
|momentum change equals
|the part of an equation that cannot change ex:percentages
|searching for an answer
|the unit for work and all forms of energy
|unit of mass (kg)
|something in motion
|energy in motion
|equation for kinetic energy
|law of conservation of momentum
|in the absence of a net force, the momentum of an obeject of system is unchanged.
|a measurement without direction(how big,long,ect.)
|a measurement of ones inertia and how much matter an object has.
|plural of momentum
|the product of mass and velocity of an object has magnintude and direction (vector quantity)
|the combination of all forces action on an object
|newtons is used for
|unit for force
|for an object resting on a horizontal surface, the upward force that balances the weight of an object. (aka supporting force)
|energy the has the potential to create kenetic energy. ex: rollercoaster at top of hill
|equation for potential energy
|any object that moves through the air or space, acted only by gravity, can be air resistance
|rate at which work is done or energy is transformed.
|equation for power
|from the center of a circle to the outside
|a number times 10 to the power of something (negative= decimal, positive=positive) ex: 2.4 x 10^4 = 24,000
|an arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity
|speed together with the direction of motion
|up and down
|space that occupies an object.
|the force on a body due to gravity
|the product of the force on an object and the distance through which the object is moved.
|work is measure in Joules
|W= Force (distance)
|the place on a graph where x=0
|newtons 1st law
|a force will remain constant unless acted upon an outside force
|newtons second law
|newtons 3rd law
|each force has an equal an opposite force
