Conceptual Question: Use Newton's First Law to explain why there must be a force constantly acting...
object's acceleration is inversely proportional to According to Newton's second law, an 1. the net force acting on it. 2. its mass. 3. None of the above. 4. its velocity. 5. its weight. OUECTIONLO Action-reaction forces 01. Are equal in magnitude-opposite in sign 2. Have units of kilograms. 3. None of the above. 04. All of the above. 5. Always act on the same object.
Please tell me correct answer and explain!
An asteroid is moving with a speed v in space, very far from any massive objects. Newton's first law of motion says that the asteroid will slow down since there are no forces acting on the asteroid. the asteroid will speed up since there are no forces acting on the asteroid. o the asteroid will continue to move with a speed v since there are no forces acting on the asteroid. the asteroid...
Large objects have inertia and tend to keep moving-Newton's first law. Life is very different for small microorganisms that swim through water. For them, drag forces are so large that they instantly stop, without coasting, if they cease their swimming motion. To swim at constant speed, they must exert a constant propulsion force by rotating corkscrew-like flagella or beating hair-like cilia. The quadratic model of drag given by the equation, D⃗ = (12CρAv2, direction opposite the motion), fails for very...
In words, define the term force; explain how mass can be used to define the force unit Newton Name and draw all of the significant forces that act on any common object (such as an airplane in flight) Explain what is meant by the normal force, and be able to draw it and calculate it for common objects Explain in your own words all three of Newton's Laws of Motion Use Newton's Laws to explain how any object will behave...
Part I - Newton's First Law Make sure the boxes that say “Force” and “Speed” are checked. a. Apply a force of 50 N right to the box. Describe the motion of the box using physics terms (i.e. velocity, acceleration, displacement). Refer to the speedometer in your answer. b. Reset the scenario (don't forget to check force, speed again). Apply a force of 50 N to the right for about 5 seconds then reduce the applied force to zero (the...
Question 7 is related to the force vs mass graph that is
provided and the first section of the excel sheet. Question 3 has
to do with the force bs acceleration graph and second section of
the excel sheet. The first two files are showing the equations that
are supposed to be used to find these answers. Any help would be
greatly appreciated.

understanding newton's law 1. An object cannot remain at rest unless which of the following holds? a. The net force acting on it is zero. b. The net force acting on it is constant and nonzero. c. There are no forces at all acting on it. d. There is only one force acting on it. which one is the answer? there can be more than one answer.... 2. If a block is moving to the left at a constant velocity,...
4. Newton's Third Law You will now attempt to measure the forces objects exert on each other when the objects interact and the effects those forces have on the motion of the objects. In this section, you will use both force sensors on two carts and conduct a series of force measurements during (gentle) tug-of-war tests. 4.1: Suppose you have two carts, A and B. Both are made of the same material, and B is more massive (heavier) than A....
tonHint: The assumption was not "it's moving in a circle."1 2. Claiming that a particle is moving in a circle with a constant radius is logically/mathematically equiv- 3. Consider a particle moving in a cirele of radius R. How is it posible for the particle to experience an 4. After deriving the formula for centripetal acceleration, we were inspired by Newton's d Law to alent to two other claims. State at least one of those claims. acceleration when its speed...
A common misconception about Newton’s first law is that when no net force acts on an object, the object must be at rest (i.e. stopped). Here, we will illustrate an example that shows this conception to be false. When a skydiver jumps out of an airplane, she is initially in free-fall and therefore has a downward acceleration of one ‘g’ due to the force of gravity. As she falls, gravity speeds her up. But the faster she goes, the more...
