To analyze the given information and answer the questions, let's break it down step by step:
1: Earth’s gravity causes both objects to fall at the same rate.
This statement is a fundamental principle of gravity. It is commonly known as the "equivalence principle," which states that in a vacuum, all objects fall with the same acceleration due to gravity, regardless of their mass or composition.
2: Gravitational acceleration is irrespective of mass.
This statement is correct. According to Newton's law of universal gravitation, the force of gravity acting on an object depends on the mass of the object it is being attracted to. However, the acceleration due to gravity is the same for all objects near the Earth's surface, regardless of their mass. It is approximately 9.8 m/s^2.
3: Object 1 has more surface area than object 2.
To determine whether object 1 has more surface area than object 2, you need to compare their respective sizes and shapes. Surface area is the measure of the total area that an object covers. It can be calculated using specific formulas for different geometric shapes. If you have the dimensions or shape details of objects 1 and 2, you can use these formulas to compare their surface areas.
4: The company can design a parachute with more surface area.
Designing a parachute with more surface area is indeed possible. A parachute works by increasing the air resistance or drag acting on it. Increasing the surface area of a parachute creates more air resistance, which helps to slow down the falling object. However, the design of a parachute involves various factors, such as the weight of the object, desired descent speed, materials used, etc. A parachute's size and surface area must be balanced with these factors to ensure safe descent.
5: Drop each object 10 times and use the average of each object’s fall times.
Dropping each object multiple times and using the average of their fall times is a valid method to compare how fast objects fall. By conducting multiple trials and taking the average, you can reduce the impact of random errors or variations in individual trials, obtaining a more reliable measurement. To get the fall time, you can use a stopwatch or an accurate timing device to measure the time it takes for each object to reach the ground.
