Problem: How does the increase mass affect acceleration and the force of the accelerating object?
Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.
Hypothesis: As the Mass increase so will the force.
Variables:
Independent Variable – The amount of mass tied at the end of the string
Dependent Variable – Force (worked out by acceleration)
Controlled Variable – Same amount of air resistant (stay in the same room), same surface of what the trolley is going to accelerate on, same trolley, have the string equally stretched out every time and same tick rate of the ticker timer. The controlled variable will be controlled to create a fair test.
Apparatus:
* Power Pack
* Ticker Timer
* Ticker Tape
* Trolley
* 1 meter string
* Pulley wheel
* 50 gram weights x10
* Ruler
* Calculator (recommended)
* Sticky tape
Procedure:
(To be done on bench)
1. Plug the power pack into a power source.
2. Attach the power pack to the ticker timer, by attaching 1 plug from the black (negative) output of the power pack to one of
Newton 's three laws of motion play a huge role in our everyday life; from driving down the road and catching a baseball. Newton’s laws help us fully understand gravity, motion, and force in three easy-to-understand laws.
The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how
If the resultant net force acting on the cart increases and total mass remains constant, than the acceleration will increase proportionally because Newton’s second law of motion states that acceleration is equal to the net force over the mass of the system; this demonstrates a directly proportional relationship between acceleration and net force because when acceleration increases, so does net force (Newton’s second law).
where F is force (5N) , m is mass (5kg), and a is acceleration (you have to find acceleration)
Force is equal to the mass of an inert object multiplied by the acceleration of that body
1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.
To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.
13. Find the acceleration of a forklift of mass 1400 kg pushed by a force of 2100 N that is opposed by a frictional force of 425 N.

The work offers an exact quantitative description of bodies in motion in three basic laws. The first law, known as the Law of Inertia, states that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law states that acceleration is produced when a mass is acted on by a force. The greater the mass of the object, the greater the force required to accelerate it.
The purpose of this experiment was to determine if rubber bands or bungee cord would put more force into the launch of the catapult. The experiment was designed to test the hypothesis if either a bungee cord or rubber bands would help an eraser to launch further, because of more force.
1: Gather all the materials needed for the experiment (a meter tape, a ramp, 2 carts with wheels and without wheels, a rubbermat, 5-gram masses, tape, a triple beam balance, a calculator, and 2 other people to help you [Person 1 and Person 2]).
3. What happens to the total force as the muscle length is increased from 50mm to 100 mm?
The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of
