Premium Velocity Acceleration
quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity. Sports announcers will occasionally say that a person is accelerating if he/she is moving fast. Yet acceleration has nothing to do with going fast. A person can be moving very fast and still not be accelerating. Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity‚ then the object is not accelerating. The data at the right

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also‚ we verified the angle at which the projection of the ball would produce a maximum range. Lastly‚ we predicted the range that a ball would travel at a certain angle‚ theta. Projectile motion is the motion of objects that are initially launched‚ or projected‚ and then continue moving with only the force of gravity acting upon it. The forces involved in projectile motion are the initial velocity of the

of motion that consists of horizontal and vertical motions which are independent from each other‚ known as vector components. For an object to be considered a projectile‚ it must not be self-propelled. Projectiles move horizontally at a constant velocity. However‚ they undergo uniform acceleration in the vertical direction‚ which is caused by gravity. An important aspect of projectile motion is that the time it takes for the object to travel on the Y axis is exactly the same as the time it takes
Premium Classical mechanics Acceleration Velocity
an object moves at a constant speed along a circular path. Velocity is always tangent to the path in circular motion. Speed is constant‚ velocity is not. Centripetal Acceleration‚ – acceleration that maintains the object along a circular path directed towards the center. Also called as radial acceleration. In 1673‚ Christian Huygens‚ determined the following relationships. Velocity‚ Where‚ r = radius of curvature/path‚ t = time/period. Frequency (f) – number

Objective: To study the relationships between position‚ velocity‚ and time‚ with acceleration held constant‚ of an object moving in one-dimensional motion with minimum friction. A motion sensor will be used to measure various aspects of vector quantities. Description: An Air Track is positioned along the edge of the table. It is a long straight metal beam with many small holes that are roughly each 2mm in diameter. It is positioned at an angle to allow the gliders to glide down the slope

Last week‚ my group and I were constructing the roller coaster. I contributed by installing my funnel into the coaster. I did this by making adjusting the track so that it would lead the marble to the border of the tube. I did this because learned that when the marble spins around the edge of the tube‚ it increases the time which was what we wanted. After adjusting‚ I put supports on the funnel that would help the funnel maintain its shape to have the most maximum time possible. I also contributed
