Would a parachutist be considered a free falling object and why?
The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).
An egg is free-falling from a nest in a treeNeglect air resistanceDiagram the forces acting on the egg as it falls?
The forces acting on the egg are gravity pulling it downwards and the normal force pushing it upwards. The normal force is exerted by the branch of the tree the egg is falling from, preventing it from falling through the branch.
What acceleration does a parachutist have when falling before opening the parachute?
A parachutist falling before opening the parachute experiences an acceleration due to gravity of approximately 9.81 m/s^2, which is the acceleration due to free fall. This acceleration causes the parachutist's velocity to increase as they fall towards the ground.
When the only force acting on a falling object is air resistance the object is said to be in free fall true or false?
False. When the only force acting on a falling object is air resistance, it is not considered to be in free fall. Free fall occurs when an object falls solely under the influence of gravity with no other forces acting upon it.
What term describes an object that is falling and the only force acting on it is gravity?
Free fall describes an object that is falling and the only force acting on it is gravity. In free fall, the object is accelerating downward due to the force of gravity without any other forces affecting its motion.

Is a rain drop falling from the sky a free fall?
Yes, a raindrop falling from the sky is considered to be in free fall because it is only under the influence of gravity with no other forces acting on it.
What is free falling rocks?
Free falling rocks refer to rocks that are falling due to gravity, without any external forces acting on them. This phenomenon can occur naturally during rockslides, landslides, or when rocks become dislodged from a cliff or steep slope. Free falling rocks can pose a danger to people and structures in the area below.
How can a free body diagram be used to analyze the forces acting on a loop in a roller coaster?
A free body diagram can help analyze the forces acting on a loop in a roller coaster by showing all the external forces acting on the loop, such as gravity, normal force, and tension. This diagram can help determine if the loop will have enough speed to complete the loop without falling off or if additional forces are needed to keep the riders safe.
What are some examples of gravational energy?
Examples of gravitational energy include a book resting on a shelf, water held in a dam, and a roller coaster at the top of a hill. In these situations, potential energy is stored due to the gravitational forces acting on the objects.
What is the free body diagram of a body falling freely?
A free body diagram is a representation of how the forces that are acting on a point or particle interact. You place your point at the origin and then draw your forces with their tails placed at the point
When an object is free falling it has what?
When an object is free falling, it has only the force of gravity acting on it. This causes the object to accelerate downwards at a rate of 9.8 m/s^2 (on Earth). At the same time, the object experiences no air resistance or external forces influencing its motion.
Free falling objects accelerate at about 10 ms because the forces of friction and air resistance act on them true or false?
False. Free falling objects accelerate at a rate of 9.8 m/s^2 due to the force of gravity acting on them. The force of friction and air resistance do not significantly affect the acceleration of free falling objects in a vacuum.
