Answer:
The 2 forces are a Push and a Pull
Mass is the resistance of change in speed or position when adding force.
Weight is the force of gravity
Tension Force is the pulling force transmitted through a string cable or chain. The formula for this is T = mg + ma.
It gives the particle the same acceleration as all those actual forces together as described by the Newton's second law of motion.
An unbalanced force is when there is 2 forces on opposites of an object both are adding force but one side is stronger than the other.
Friction is a force that heats things up. This happens when we rub our hands together and the heat that is generated from the friction makes our hands warmer.
Static friction is what keeps the box from moving without being pushed, and it must be overcome with a sufficient opposing force before the box will move. Kinetic friction (also referred to as dynamic friction) is the force that resists the relative movement of the surfaces once they're in motion.
