This is General Physics. I need your help. Hoping easy to read and understandable. I will be waiting patiently for your answer. Thankyou in advance.
Newton's laws of Motion Law of Momentum Conservation 1. What are the two claims and the one condition that are stated in Newton's 1. What is meant by the law of action-reaction? first law? 2. How does the momentum conservation principle emerge from the law of 2. What does Newton's first law mean when it comes to predicting the action- reaction? motion of an object? 3. What does it mean to say that momentum is conserved? 3. What claims does Newton's second law make regarding the acceleration of Problems: objects? L. Find the momentum for each object. 4. How can Newton's second law be used to make comparisons of a. A 500kg car traveling at 20 m/s. acceleration values, to predict an acceleration value, or to predict how an b. A 0.10 kg fish swimming at a velocity of 8 m/s. object will move? . A 75kg man running at a speed of 7 m/s. 5. In what way does Newton's third law of motion describe the nature of a force on an object? Static Equilibrium 6. How can Newton's third law and Newton's second law be combined to 1. What is meant by saying "an object is at equilibrium"? describe the magnitude of the force and the acceleration of two interacting 2. How do you mathematically analyze the forces on an object that is at objects? equilibrium? Problems: Problems: Three forces F1 = (25.ON, 42.5. ), F2 = (15.5N, 215 ), and F3 = (20.5N, 155 ) T1 T2 35 350 accelerate a 12 kg mass. What is the net force acting on the mass? What is Compute the force acting on the magnitude and direction of the mass's acceleration? What would have to be 24 N the magnitude and direction of a fourth force F4 so that the acceleration of the mass Newton's Laws of Universal Gravitation would be zero? 1. What is the conceptual meaning of Newton's Law of Universal Gravitation? 2. How is the Law of Universal Gravitation used to solve Physics word Mechanical Energy Conservation problems? 1. Under what conditions is mechanical energy conserved? Problems: 2. What is meant by saying that mechanical energy is conserved? Two spherical objects have masses of 3.2 x 106 kg and 6.5 x 104 kg. The Problems: gravitational attraction between them is 75 N. How far apart are their An ice skier sliding from a height of A, as shown in the figure below. If the centers? initial velocity = 0 and acceleration due to gravity is 10 m/s2, then what is the velocity of the skier at point B Kepler's Laws of Planetary Motion 1. What are Kepler's three laws of planetary motion and what is their significance? Problems: The mass of the Moon is 7.3477 x1022 kg, the mass of Earth is 5.972 x1024 kg, and the mean distance of the Moon from the center of Earth is 384, 400 km. Use these data to calculate the magnitude of the gravitational force exerted by Earth on the Moon
