I need help on these problems it doesn’t have to be all of them I would appreciate it.

I PRELIMINARY QUESTIONS 1. One of the timing devices Galileo used was his pulse. Drop a rubber ball from a height of about 2 m and try to determine how many pulse beats elapsed before it hits the ground. What was the timing problem that Galileo encountered? 2. Now measure the time it takes for the rubber ball to fall 2 m, using a watch or clock with a second hand or seconds display. Did the results improve substantially? 3. Roll the hard ball down an incline that makes an angle of about 10° with the horizontal. First use your pulse and then your watch or clock to measure the time of descent. 4. Do you think that during Galileo's day it was possible to get useful data for any of these experiments? Why?

What I Have Learned Directions: Read and understand carefully the givern paragraph. Then, complete the statements given below. Write your answers in your notebook/ on a separate sheet of paper. Accelerate Charts Diagrams Dot dingram Force Motion Motion graphs Point of reference Position Time (1) say that something has moved, you are describing motion. The greater the (2 is a change in position in a certain amount of time. When you acting on an object, the more it will (3) defined as something that is used to judge or understand something else. A (4) In describing motion, you are comparing it with some frame of reference Motion can be described by using visual representation like (5) and (7) Motion dingram or (8) can al provide data if the object is moving with a constant velocity or accelerating. It ca be represented using tape or oil drop diagrams. You cani also describe motion using charts or graph that can provide the apecific position of an object at a giv time by creating (9). -…

please help me with drawing the Distance vs time graph for the freefall motion and the speed vs time graph and then answer the two questions on the chalk board

UNIT 1: Motion and Its Applications 1. Know terminology i.e. displacement, distance, uniform motion, constant velocity, speed, velociy, acceleration, inertia, mass, net force, normal force, applied force, frictional force, coefficient of friction, gravity, etc. 2.

Be able to solve distance, displacement, speed, velocity, and acceleration problems using kinematics equations 5. Be able to interpret graphs: determine direction of motion, slowing down, etc. and solve for quantities from the graph Ad, At, v, a, etc. 6. Explain Newton's 3 Laws of Motion; know examples of each 7. Solve force of gravity problems 8. Solve friction problems using coefficient of friction 9. Be able to draw FBDS showing all forces 10.

Find the following using the photo below. a. If v = (5s) m/s, where s is in meters, determine a at s = 1 m.b. If a = (9t2) m/s2 determine v when t = 1 s if v = 0 at t = 0.c. If s = (3t2 + 2) m, determine v when t = 2 s.d. If a = 2 m/s2, determine v when t = 2 s if v = 0 when t = 0.e. If a = 2 m/s2, determine v at s = 4 m if v = 3 m/s at s = 0.f. If a = 4 m/s2, determine s when t = 3 s if v = 2 m/s and s = 2 m when t = 0.g. When t = 0 the particle is at A. In four seconds it travels to B, then in another six seconds it travels to C. Determine the average velocity and the average speed. The origin of the coordinate is at O.

Keeping the total mass constant 1.  Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? 2.  Did a change in the net force produce a change in acceleration by the same factor? Do your results agree with Newton’s 2nd Law? 3.  Make a plot of Net Force vs. Experimental Acceleration and draw the best fitting line.
