velocity
At 180 degrees the net force is at a minimum; the two are working against one another.
Ferns produce spores to reproduce, flowering plants produce seed.
No. Any object that is hot enough will produce light, regardless of what heated it.
An object that will stop the flow of a current is called a switch.
velocity
Reflection
That's called a 'balanced' group of forces. Their effect on the object's motion is the same as the effect of zero force ... the object may rotate, but it won't accelerate.
net
The object's dimensions. Multiplied together they give the objects volume.
force
Electrostatic induction allows an object to produce a charge in another object without touching.
Net Force.
A torque acting on an object tends to produce rotation.
Static Electricity!
