What is an object in free fall will accelerate toward the earth at 9.81MS's?
An object in free fall will accelerate towards the Earth at a rate of 9.81 m/s^2, due to the gravitational force acting on it. This acceleration is constant for all objects in free fall near the surface of the Earth, regardless of their mass.
What is the parachutes purpose?
The reason parachutes were designed was so that people could fall at any height and not get hurt at all.
What is the manipulated variable in a controlled experiment in which a scientist is studying how long it takes a parachutes of different sizes to fall to ground?
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.
Why do parachutes accelerate and then fall at a constant speed?
This is because the parachute will trap air underneath it and so the force of air resistance will increase, and it will take longer to fall. The bigger the air resistance the quicker the terminal velocity is reached.
What causes the parachutes to fall at different speeds?

how to test if parachutes fall faster or slower when the person is heavier?
.
What do falling objects accelerate at a rate of?
Falling objects accelerate due to gravity at a rate of approximately 9.8 m/s^2 near the surface of the Earth. This acceleration is constant and causes objects to increase in speed as they fall.
How do objects in free fall in a vacuum accelerate?
Objects in free fall in a vacuum accelerate due to the force of gravity acting on them. In the absence of air resistance or other external forces, the only force acting on the object is gravity, causing it to accelerate at a constant rate of 9.8 m/s^2 towards the Earth's center.
In a controlled experiment a scientist is studying how long it takes parachutes of different sizes to fall to the ground what is the variable?
The variable being studied is the size of the parachutes.
Why speed of parachutes becomes constant?
As a parachute falls, air resistance pushes back against it, creating an upward force called drag. This drag force increases as the parachute gains speed, eventually balancing out the force of gravity pulling it down. When these forces are in equilibrium, the parachute stops accelerating and falls at a constant speed known as terminal velocity.
When does an object fall at a constant rate of acceleration?
An object falls at a constant rate of acceleration when it is in a vacuum or when air resistance is negligible. In this case, the only force acting on the object is gravity, causing it to accelerate towards the ground at a constant rate of 9.81 m/s^2 (on Earth).
How is gravity related to free fall?
Gravity and free fall are similar because they are both a force that pulls objects downward. <><><><><> Gravity is the force that pulls you down. Free fall is when you have no opposing force keeping you up.
