observations

At which temperature would it take the longest for the smell of cologne that someone is wearing to reach you

-30 degree C --APEX:)

Is the term used to describe the study of motion

kinematics

A soccer player sprinting down the field demonstrates which form of energy

kinetic

What the the two main states of mechanical energy

Potential energy and Kinetic energy

What is an example of conditions not producing work

the momentum must be greater than the force . the force may be very large

How much work must be done on a 5 kg snowboard to increase its speed from 2 ms to 4 ms

work=mass*speed,5*2=10

The acceleration of gravity means that for each second that passes falling objects move 98 meters

No, that's not correct.

The acceleration of gravity means that for each second that passes, falling objects fall

at a speed that's 9.8 meters per second fasterthan it was one second earlier.

How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent

If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.

Whih of the following is not a reason why gravity is important in our lives

It keeps water molecules together in a cup.

What do we call a collection of matter that does not interact with anything else in the universe

An isolated system I think
