1. Answer the following about gravity and acceleration.
a) There are 2 aspects of acceleration. The first one is when an object is moving in a straight line and changing (starts with "s") and the second one is when an object is moving at a constant speed and changing (starts with "d"). What are the 2 aspects?

b) Is it true that the net force on an object and its acceleration are proportional to each other? What about the vectors representing the net force on an object and its acceleration will look similar (as in same direction but different lengths)?

c) When a curve is "sharp" we say it has a small "radius pf curvature" and a "gentle" curve has a large "radius of curvature." When you are in a car going around a curve, what two aspects of the car's motion affect the sideways force and acceleration you experience in the car?

d) The formula for Newton's Law of Gravitation is F=G((Mm)/r^2), what direction is the force on "m"? What about on "M"?

You're watching a car race and observe one of the cars going around a banked circular curve. The bank is tilted at about 20 degrees, meaning that the car is tilted sideways by this much while driving around the bank. The curve seems to be a semicircle in shape, and you see the radius of the curvature is about 18.0 m. a. If the car's tangential speed is constant, then why does the car feel acceleration? b. Draw a force...

Notice that the final answer for the acceleration depends only on g and the angle θ, not the mass. Equation (2), which gives the normal force, isn't useful here, but is essential when friction plays a role.

PLEASE ANSWER BOTH QUESTIONS! (1) A 2.4 kg particle moves along an x axis, being propelled by a variable force directed along that axis. Its position is given by x = 3.0 m + (4.0 m/s)t + ct2 - (1.8 m/s3)t3, with x in meters and t in seconds. The factor c is a constant. At t = 3.0 s, the force on the particle has a magnitude of 36 N and is in the negative direction of the axis....
