Velocity is a measure of how fast an object is moving in a particular direction. It is a vector quantity, meaning it has both magnitude (speed) and direction.
Velocity is calculated by dividing the displacement (change in position) of an object by the time it took to travel that distance. The formula for velocity is v = d/t, where v is velocity, d is displacement, and t is time.
The angle of a ramp can affect the velocity of a puck by changing the force of gravity acting on the puck. A steeper ramp will have a greater gravitational force, resulting in a faster velocity for the puck. Additionally, the angle of the ramp can also affect the direction of the puck's velocity.
The mass and friction of the puck, as well as the texture and incline of the ramp, can also affect the velocity of the puck. The amount of force applied to the puck and any external forces acting on it can also impact its velocity.
Velocity can be measured using a variety of methods, such as using a stopwatch to time how long it takes for the puck to travel a certain distance on the ramp. Another method is using sensors to track the displacement and time of the puck's motion, which can then be used to calculate its velocity.
