If an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.
Unbalanced Force:
The unbalanced force is the magnitude of the net force that tends to cause the motion of objects. It is nothing but the greater amount of force to be applied to the object to displace the object in either direction.
If an object is moving, stopping, changing the speed, or changing the direction, then such activities directly show that the object is changing its state of motion. And the change in the motion is only caused when there is some magnitude of force associated with it.
- When the magnitude of forces applied on an object such that one force is greater than another in a specific direction, then such forces are known as unbalanced forces.
- Unbalanced forces cause motion, which means a body can move, stop or even can change its direction due to the unbalanced force.
Thus, we can conclude that if an object moves, stops, changes speed, or even changes direction, then that condition represents the unbalanced force condition.

Decomposition reactions are said to be those reactions in which a reactants breakdown into two or more products. The general reaction for decomposition reactions is as follow,
ABC → A + B + C
Specific Examples are as,
Water → Hydrogen + Oxygen
2 H₂O → 2 H₂ + O₂
Calcium carbonate → Calcium oxide + Carbon dioxide
CaCO₃ → CaO + CO₂
While, Synthetic reactions are said to be those reactions in which two or more reactants combine to form two or more products. The general reaction for synthetic reactions is as follow,
A + B + C → ABC
Specific Examples are as,
Iron + Oxygen → Iron Oxide
2 Fe + 3 O₂ → 2 Fe₂O₃
Sodium + Chlorine → Sodium chloride
2 Na + Cl₂ → 2 NaCl
Sulfur + Oxygen → Sulfur dioxide
S + O₂ → SO₂
Potassium + Chlorine → Potassium chloride
2 K + Cl₂ → 2 KCl
1) Vf = Vo - gt; Vf = 0 => Vo = gt = 9.8m/s^2 * 1.5s = 14.7 m/s
2) d = Vo*t - gt^2 /2 = 14.7m/s*1.5 - 9.8m/s^2 * (1.5s)^2 / 2 = 11.02 m
Wouldn't everything fall?
