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...

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...

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.

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....

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...
