An applied force is the force exerted on an object with the intent to move it. Frictional force is the force that opposes motion. Static friction acts on objects at rest and prevents them from moving. Kinetic friction acts on objects in motion and works in a direction opposite to the motion. Air resistance is a kind of friction exerted by air on moving objects. Normal force is exerted on an object by the surface it is resting on to support its weight. Spring force is exerted by either a compressed or stretched spring. Tension force is the force acting on a rope or a string that is pulled tight by a load attached to it. Gravitational force is the attractive force that acts between two objects. It is directly proportional to the mass of the object, which means that heavier objects have a more pronounced gravitational force. Magnetic force is the force between two magnetic poles, which may be attractive for unlike poles or repulsive for like poles. Electrical force is the force between two electrical charges, which also may be attractive for unlike charges and repulsive for like charges.

Gekata [30.6K]

Answer: Scientific reasoning

Explanation:

A scientific reasoning can be defined as the justification which connects the evidence with that of the claim and it rules out all those claims that are not supported by any evidence. It explains the fact that how evidence can support a claim and scientifically acceptable conclusion can be drawn. An argument is always based on one or more claims which can either be true or evidentially proved.

<span>Percent yield is the measured recovery of a substance in grams divided by the theoretical amount of substance expected in grams (times 100 to convert to %). Undissolved Aluminum trihydroxide would add mass to the Aluminum sulphate one is making here. The measured mass would be inaccurately high, increasing the percent yield calculated.</span>
