which term explains whether an object's velocity has increased or decreased over time
you're fishing for "acceleration", but your description doesn't support that answer.
acceleration is also present if the direction of motion has changed, even if the speed
(the size of velocity) hasn't changed.
which of these is a characteristic of nonmetals
what is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms
what term is used to describe splitting a large atomic nucleus into two smaller ones
which type of reaction is the burning of gasoline to release heat energy
a car travels 65 km in 1 hour what is its average speed in meters per second
what is the momentum of a truck with a mass of 4500 kg traveling at 25 ms
what is the term that describes an object's mass per unit volume
density.. for example, 15 kilograms per meter cubed
what are the three main classes of elements
the are metals, metalliods, non-metals
resultant velocity is calculated using which two math functions
"addition and subtraction"
resultant velocity refers to the sum of all vectors in an equation. the two math functions that are used to calculate the resultant velocity are addition and subtraction.
a box weighs 35 n with gravity applying that force downward if you apply 39 n upward force to pick it up what is the net force applied
which of these is the best description of an atom
the smallest particle that retains unique chemical
when two dogs are tugging on the same bone in opposite directions what are they producing
how can the equation force equals mass x acceleration be rewritten
equation: force=mass x acceleration
if you are looking for the force, use the equation as is.
to find the following, it's assumed that you are given the other two values:
mass= force / acceleration
acceleration= force / mass
remember your labels in your calculations.
mass= force x acceleration
force = mass x acceleration
mass = force / acceleration
acceleration = force / mass
- since acceleration = velocity / time we can also substitute velocity / time for acceleration in any of the above.
- since velocity = speed / time, we can also substitute speed / time for velocity or speed / (time * time) for acceleration in any of the above.
which of these would be expected to increase the rate of sa chemical reaction
an enzyme or other catalyst
what is another term useed to describe the group of elements in columns of the periodic table
vertical columns are called groups.they are also called
families. there are 18 groups in periodic table.
what is the calculation of mass x acceleration applies to which of newtons laws of motion
newton's second law: force = mass x acceleration
which of these would you expect to have the most frictional force against movement
how much force is needed to accelerate your body at a rate of 2 ms and sup2 if you weigh 45 kg
force = mass x acceleration = 45 x 2 = 90 newtons
