In Physics, 'work' has a very clear definition:
It's (strength of a force) times (distance through which the force acts).
'Work' has the units of Energy.
If you push against a shopping cart with 30 newtons of force, and
you keep pushing while the cart moves 4 meters, then you have
done (30 x 4) = 120 newton-meters of work = 120 "Joules".
Physical characteristics of matter include its mass<span>, weight, volume, and </span>density<span>. It also specifically describes its odor, shape, texture, and </span>hardness<span>. In addition, physical properties describe whether the object is a solid, a liquid, or a gas – its phase of matter at room temperature.</span>
I think force is something to do with a force being applied to a movement or is just to pull but not sure sorry if this aint right
Birds are warm-blooded, which means they need to move and eat more in the cold to stay warm; snakes are cold-blooded, so they don't have to.
