it's an exam question from very old paper - not recent. that's all there is to the question. could you help with explaining the cases and reasonsSteamKing said:
To me, these questions seem self-explanatory. If you have a specific question about something which is unclear, I'll try to help. But simply saying 'Explain this' is too vague.PhysicStud01 said:
the 2 parts of (d). could you explain. like give the reason and what I should have known to arrive that the conclusion (reason)SteamKing said:
Well, what happens when you shoot something out of a gun? Study the details given in section (c) and ask yourself if it would be safe for a man inside the spacecraft to be shot out of a gun.PhysicStud01 said:
thanks a lot. but sorry, i still can't figure it outSteamKing said:
(d)(i) Think about forces.PhysicStud01 said:
Dynamics in physics is the study of how objects move and the forces that cause that movement. It involves understanding the motion of objects and how they interact with their environment.
To solve a dynamics problem, you first need to identify all the known and unknown variables, such as mass, acceleration, and force. Then, you can use Newton's laws of motion and other relevant equations to analyze the problem and find the solution.
Kinematics is the study of the motion of objects without considering the forces that cause that motion. Dynamics, on the other hand, focuses on the forces that affect an object's motion. In short, kinematics describes how objects move, while dynamics explains why they move.
Some common examples of dynamics problems include calculating the acceleration of a car on a curved road, predicting the trajectory of a ball thrown into the air, and determining the force needed to lift an object off the ground.
Understanding dynamics is crucial in many fields, such as engineering, physics, and mechanics. It allows us to analyze and predict the behavior of objects in motion, which is essential for designing structures, machines, and vehicles. Dynamics also helps us understand the natural world and the laws that govern it.
