Mass and Gravitational Potential Energy

5. Record the effort force shown on the Newton Scale in newtons while pulling the cart up the inclined plane.

4. Place the mass on the bottom of a ramp and attach the loop of string to the

15) A cart starts from rest and accelerates at 4.0 m/s2 for 5.0 s, then maintain that velocity for 10 s, and then decelerates at the rate of 2.0 m/s2 for 4.0 s. What is the final speed of the car?

An unknown force pushes a 17 kilogram block across a smooth (frictionless) floor. Three seconds

2. For the flyer to have her center of gravity reach 25 feet, what does the initial velocity need to be?

block is moving with a speed of 6 meters per second. What is the magnitude of the unknown force?

The greater the incline and greater the height, the greater the acceleration of the cart. -This experiment measured the acceleration of a cart moving down a sloped track in order to find a relation between the acceleration of an object and the sine of the angle at which it is moving. There were three separate experimental stages, with the variable being the angle at which the

After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v​i​​+at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

A net force of 5.0 N moves a 2.0-kg object a distance of 3.0 m in 3.0 s. How much work is done on the object?

Kinetic and potential energy are convertible while negative work is done by consuming energy, and positive work is done by absorbing energy.

When the roller coaster train stops, the brakes have a force when riders get on the roller coaster train or waiting for the other train to begin the ride. Newton’s 1st law represents Space Mountain going into a constant speed with the velocity or mass. The air and the train has a force to go to the same direction going forward not going backwards. Furthermore, the total velocity of Space Mountain is 35 miles per hour. When I divide the mass with its velocity, I get 7 for the weight..to change the motion.

Then I used the work-energy theorem to calculate the energy lost as heat, the work, as an object traveled a given distance on a sticky surface. Friction was a factor in that part of the problem so I drew a free-body diagram to indicate the net force acting on the object (WA-COMP-2009.SCI.1.1.3.H). Finally, I had to calculate the spring constant using the mechanical energy equation one more time, but replacing the gravitational potential energy equation with the spring potential energy equation to determine the spring constant (WA-COMP-2009.SCI.1.1.3.J). Problem eleven required the use of one simple kinematic equation, after I applied the impulse momentum theorem; once I determined the velocity of a skater, I used it to determine the time it took him to travel a given distance (WA-COMP-2009.SCI.1.1.3). Although I lost points on three multiple choice questions, they are no longer a weakness because I reworked the problems and have become proficient

Newton’s Second Law relates force and mass directly to acceleration. In other words, an object will accelerate in the direction that the net force is applied in. The introduction of friction will balance the forces, thus completely stopping the motion of the car. As a result, the car must undergo another force for it to accelerate again. Therefore, the track is designed to give the car a forceful push soon after it stops. While the car is plummeting back down the hill, the lower track will move, so that the car will be forced to reroute, and follow a new path onto the next section of the roller coaster. The next lyrics in the song, “Slip and slide and ride that rhythm, jump and hop, hop until we drop,” will play and project in the building while the car experiences a series of small hills and dips. As the car glides down the final hill, the music will fade slowly into the next
