Yes. In fact, a body can ONLY be accelerated by outside forces.
What is the meaning of uniform accelarated motion?
Yes, if body A and body B interact with each other through forces, these forces can affect the net acceleration of the entire system. The net acceleration of the system is determined by the external forces acting on the system and the forces between the bodies within the system.
Magnetism, friction, and reaction forces in general.
They are inertia and momentum. If an object is in motion it tends to "try" to stay in motion, and an object at rest does the same to stay put. The forces still act on it, although the forces are slightly weaker.
Any medical emergency involving an injury. These emergencies tend to happen quickly and are generally caused by outside forces acting upon the body.
Balanced forces cannot bring a body to rest. Balanced forces can act on a body which is already at rest or in motion but equal forces cannot change a bodies acceleration, kinetic energy or momentum.
If the object's speed is changing, or it's not moving in a straight line, then it's accelerating.
Your skin is the largest organ outside of your body :)
The vagina connects the uterus to the outside of the body.
The scrotal sac hangs outside the body because sperm production requires a lower temperature than body temperature. However, this exposes the testes to potential injury from external forces and pathogens.
Your whole body, inside and outside, is made of cells.
