The manipulated variable in this experiment would be the size of the parachutes. By changing the size of the parachutes, the scientist can observe how it affects the time it takes for the parachutes to fall to the ground.
The variable being studied is the size of the parachutes.
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
In a vacuum, all objects fall at the same speed regardless of shape or weight due to gravity exerting the same force on them. However, in the presence of air resistance, objects with different shapes will fall at different speeds due to variations in air resistance.
The reason parachutes were designed was so that people could fall at any height and not get hurt at all.
The manipulated variable in this experiment would be the size of the parachute. The scientist would change the size of the parachutes to see how it affects the time it takes for them to fall to the ground.
.
Objects fall with different accelerations and speeds due to differences in their mass and drag forces acting upon them. The acceleration of an object due to gravity is constant (9.8 m/s^2), but objects with greater mass experience greater gravitational force and thus fall faster. Additionally, objects with larger surface areas experience more drag, which can further affect their speed of descent.
The independent variable is the size of the parachute. It is the variable that the scientist intentionally changes or manipulates in order to observe its effect on the falling time of the parachutes.
Objects fall at different speeds due to the influence of air resistance, mass, and shape. Lighter objects with a higher surface area experience more air resistance, slowing their descent compared to heavier objects with a smaller surface area. Additionally, gravitational acceleration remains constant regardless of mass, resulting in objects falling at different speeds due to these factors.
