Title
Investigating how the final velocity of an object in motion is affected by the angle of an inclined ramp on which it travels.
Research Question
How does the angle of inclination (º) of a ramp affect the velocity (m/s) of an object in motion, if calculated using the formula [V= (2s/t) –u]?
Hypothesis The prediction for this experiment is that the final velocity of an object in motion will be affected according to the angle of inclination of the ramp. The higher the inclination or greater the angle, the greater the final velocity, however, the lower the inclination, the lesser the final velocity of the object in motion.
This is assuming a object starts from rest, the final velocity of an object rolling on the ramp, when it reaches the bottom, will increase in direct proportion to an increase in the angle of inclination of the ramp, where the angle of inclination is defined as the angle between the plane of the ramp and the ground.
This is because the component of the force (the total force being the product of the mass of the toy car and acceleration due to gravity) acting along the direction of the ramp increases as the angle of inclination increases, causing the object to move faster on the inclined plane.

The change in velocity is due to the change in acceleration. Acceleration due to gravity (g) is defined as m/s2 and force can be found by multiplying mass into acceleration [Acceleration]. The downward vertical force acting on the object of mass (grams) is [m x g] therefore Force along the ramp = [mg] x sinƟ (where Ɵ is the angle of inclination in radians). As Ɵ in Sin Ɵ increases, F along the ramp increases as well, because force equals to mass times acceleration and acceleration along the plane is [g x sinƟ]. So therefore, we can say as Ɵ increases, force increases which also causes velocity to increase. [Equations Related to Acceleration and
Now To talk about the forces that allow the car to move. There are two main aerodynamic forces acting on any object moving through the air. Lift is a force that acts 90° to the direction of travel of an object. Usually we think of lift when we think of an airplane. The plane travels forward (horizontally), and lift acts 90° to that motion of travel –
For this theoretical result, the motion or speed of the marble will have different calculations. Also, the potential energy and kinetic energy of the marble will produce a mirror effect between each other respectively. From the result of the experiment, as the height of the marble increases the speed of the marble decreases at a slow rate.

Enhanced Basal Creep - Stress concentrations around the upstream side of an obstacle result in locally high strain rates which causes ice to accelerate around the obstacle. The basal ice continually modifies its shape to allow a continued sliding. This process works best when the obstacle is over 1m in size.
My task is to investigate the factors that affect the terminal velocity of a falling object.
Physics problems can be solved and worked through many different ways. For example, for the second half of the problem (when we used d = d0 + v0t + ½ at2), we could have also used trigonometry to find the height, since we already know the base of the triangle (half the distance) and the angle.
An increase in the speed and/or the amount of cross-sectional area leads to an increase in the amount of air resistance encountered.
Inclined planes are yet another simple machine that you use nearly every day. Any time you walk up a slight hill, you are using an inclined plane. Any time you ride your bike or drive your car up a hill on the way to school, you are using an inclined plane. Even when you push your grandma in her wheel chair up the handicap ramp you are using an inclined plane. So to summarize what an inclined plane actually is, it is a flat surface on an angle that is always used to multiply your force. BUT WAIT! You, Mr. Davis, and I both recently learned that that statement ISN'T always true. You concluded while watching the Olympics that snowboarding ramps aren't force multipliers, but speed multipliers. All inclined planes that are force multipliers have a length longer than their height. However, with snowboarding landing ramps, especially during the snowboard cross event, the big jumps have heights longer than the lengths. For IMA in inclined planes, you divide the length by the height, so when this scenario occurs, an IMA of less than one occurs which indicates a speed and displacement multip...

When the trolley is raised to the top of the ramp, it gains a certain
The slope of the line on a velocity versus time graph is equal to the acceleration of the object. If the object is moving with a velocity of +4 m/s or changing its velocity by 4 m/s, then the slope of the line will be +4 m/s which is the acceleration of the object. In this case the acceleration would be 100.9 cm/s when going in the positive direction and -101.86 cm/s when going in the negative direction or to the left of the
The scientific question investigated in this experiment was, “Which household object, when catapulted at a 45 degree angle, will travel the farthest?” The hypothesis in this experiment was, “If four household objects are catapulted at a 45 degree angle, then the standard white dice will travel the farthest.” The independent variable in this experiment is changing the object launched. The dependent variable in this experiment is the change in distance traveled. The control variables are using the same catapult, tape measure, location, and maintaining the same launch angle. The control group is the catapult which remains the same throughout the experiment. The experimental group consists of the four objects being catapulted. The procedures for this experiment go as follows: Step three, place an item in the cup on the arm of the catapult. Step four, pull back the arm until it cannot go back any further. Step five, carefully release the arm which will catapult the object into the air. Step six, record where the object initially lands.
the shore and slows them down as they go up the slope to the cliff.
Slope Gradient: is the steepness or inclination of a lope from a horizontal plane. It is used to predict soil patterns. Slope gradient changes along most catenas along flowlines and laterally. For example, a steep slope will cause the rate of movement of water and debris down the slope to be more rapid. Water can either infiltrate or run-off, promoting soil development when it infiltrates and does not when it runs-off, instead it may cause erosion. Therefore, steep slopes are associated with thinner soil profiles and less developed soils. According to Vreeken (1973), less water moves into and through the soil as soil gradient increases.
The speed of the run up is at a moderate pace which means that the
