Physics Kinematics: Larry's Peach

In summary, Larry's Peach moves according to the laws of kinematics in the Physics Kinematics experiment. Its velocity can be affected by factors such as the initial speed and angle of launch, as well as external forces like air resistance and gravity. The velocity can be calculated using the formula v = d/t, where v is velocity, d is distance, and t is time. In this experiment, the peach has a constant velocity and no acceleration due to the absence of external forces. It also moves in a straight line and does not change its direction of motion, but in other experiments with external forces, it may change its direction.

and solved for delta x, which is the displacement. I then used the equation delta x= Vi(delta t)+1/2a(delta t)^2 and solved for delta t. Plugging in the values, I found that the peach reaches a maximum height of approximately 2.6m.

I would also note that this calculation assumes no air resistance and a constant acceleration due to gravity. In reality, factors like air resistance and the curvature of the Earth's surface may slightly affect the peach's maximum height. Additionally, the peach's final velocity at its highest point would be 0m/s, as it stops momentarily before falling back down. This information could be useful in further experiments or calculations involving the peach's trajectory.
 

1. How does Larry's Peach move in the Physics Kinematics experiment?

Larry's Peach moves according to the laws of kinematics, which describe the motion of objects without taking into account the forces that cause the motion. In this experiment, the peach is initially at rest and then moves in a straight line with a constant velocity.

2. What factors affect the velocity of Larry's Peach?

The velocity of Larry's Peach can be affected by the initial speed at which it is launched, the angle at which it is launched, and any external forces acting on it such as air resistance or gravity. In this experiment, we are assuming these factors are constant and the peach is moving in a vacuum.

3. How is the velocity of Larry's Peach calculated?

The velocity of Larry's Peach can be calculated using the formula v = d/t, where v is velocity, d is distance, and t is time. In this experiment, the peach is launched at a known height and travels a known distance, so we can calculate its velocity by dividing the distance by the time it takes to travel that distance.

4. Does Larry's Peach have a constant acceleration?

In this experiment, Larry's Peach moves with a constant velocity, which means it has no acceleration. This is because there are no external forces acting on the peach to cause it to accelerate or decelerate.

5. Can Larry's Peach change its direction of motion?

In this experiment, Larry's Peach moves in a straight line with a constant velocity, so it does not change its direction of motion. However, in other experiments where external forces are present, the peach may change its direction of motion due to the influence of those forces.
