Explain why parachutist and snowflakes donot fall with a constantly accelerating motion?
Parachutists and snowflakes do not fall with constantly accelerating motion because of air resistance. As they fall through the air, they experience a drag force that counteracts the force of gravity, eventually reaching a terminal velocity where the forces are balanced and they fall at a constant speed. This prevents them from accelerating indefinitely.
When is an object considered to be in free fall and can you explain the concept of free fall in physics?
An object is considered to be in free fall when it is only under the influence of gravity, with no other forces acting on it. In physics, free fall is the motion of an object solely under the influence of gravity, with no air resistance or other forces affecting its motion. This results in the object accelerating towards the Earth at a constant rate of 9.8 m/s2, regardless of its mass.
Can a simple pendulum oscillate during free fall motion?
No, a simple pendulum cannot oscillate during free fall motion because in free fall, the object is accelerating due to gravity and there is no restoring force acting on the object to cause oscillations.
Which term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
Terminal velocity is the term that refers to the speed at which a falling object stops accelerating and falls at a constant rate due to the balancing of air resistance and gravitational force.
When you drop a penny what kind of motion does it have?
When you drop a penny, it undergoes free fall motion, accelerating due to gravity until it reaches terminal velocity. There is no horizontal motion involved, and the speed of the penny increases as it falls.

Gravity affects this type of motion?
Gravity affects the motion of objects in free fall by pulling them downward towards the Earth's center. This results in objects accelerating at a constant rate of 9.8 m/s^2.
Does free fall occur only when air resistance does not affect the motion of a falling object?
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.

Terminal velocity is the term that refers to the speed at which a falling object stops accelerating and falls at a constant rate due to a balance between air resistance and gravitational force.
What describes a free fall?
Free fall is the motion of an object when it is falling solely under the influence of gravity, without any other forces acting upon it. During free fall, the object is accelerating at a constant rate of approximately 9.8 m/s^2 towards the Earth's surface. Objects in free fall experience a feeling of weightlessness as they fall.
What term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
Terminal velocity is the term that refers to the speed at which a falling object stops accelerating and falls at a constant rate due to the balance of gravity and air resistance acting on the object.
Why is a skydiver not really in free fall?
A skydiver is not in true free fall because they are experiencing air resistance or drag as they fall through the atmosphere. This force opposes the motion and causes the skydiver to reach a terminal velocity, where the force of gravity is balanced by the drag force. This results in a constant downward speed rather than accelerating indefinitely.
What do you call the motion of an object with a constant acceleration?
Free fall. Airbus has built aircrafts that may dive with an acceleration of 9.81 m/s2 to simulate zero gravity. satellites are technically in a constant free fall. A world where no friction would occur would lead to constant acceleration as long as the force acting on the object stays the same.
