When a rocket rises what is the reaction force?
When a rocket rises, the reaction force is the force pushing downwards on the rocket caused by the expulsion of exhaust gases in the opposite direction. This reaction force propels the rocket upward according to Newton's third law of motion.
Why does water go higher up a straw?
Water rises up a straw due to capillary action, which is the result of adhesive forces between the water molecules and the material of the straw. This causes the water to climb up the walls of the straw, against the force of gravity.
What is it called when water rises against gravity?
Capillary action is when water rises against gravity due to the interaction between the water molecules and the surface of a narrow container, such as a straw or plant roots. This phenomenon occurs because the adhesive forces between the water and the container's surface are stronger than the cohesive forces between the water molecules.
What forces is acting when 2 people is on the sea-saw in unbalanced forces?
When two people are on a seesaw and one side is lower, the unbalanced forces are gravity acting on the people's masses. The force pulling down on one side causes it to lower while the other side rises, creating an imbalance.
Why does the liquid in the reservoir go up the tube?
The liquid rises up the tube due to capillary action, which is the ability of a liquid to flow in narrow spaces without the assistance of external forces like gravity. This occurs because the adhesive forces between the liquid and the tube are stronger than the cohesive forces within the liquid itself.
