A Golf ball will reach terminal velocity before a Styrofoam ball. This is because the golf ball is denser and has a smaller surface area relative to its mass, allowing it to overcome air resistance more effectively. The Styrofoam ball, being lighter and having a larger surface area relative to its mass, experiences greater drag, which slows its fall. Consequently, the golf ball will accelerate to its terminal velocity faster than the Styrofoam ball.

What is the terminal velocity of a falling object on earth?
An object that has reached its terminal velocity is going at a constant velocity. Acceleration is the rate of change of the velocity. The rate of change is zero. Therefore, the acceleration is zero.
What is velocity at which a falling object travels when the force of air resistance matches exactly the downward force of gravity?
newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity
Who discovered terminal velocity?
Terminal velocity was first described by Sir Isaac Newton in the 17th century. He demonstrated that as an object falls through a fluid, such as air, it experiences drag force that increases as its speed increases. Eventually, the drag force will equal the force of gravity, causing the object to stop accelerating and reach a constant velocity known as terminal velocity.
What happens when you shoot an arrow straight in the air?
An arrow shot vertically into the air will lose velocity and reverse direction. When it begins to descend, the fletching will quickly cause it to re-orient with the point downward. It will accelerate until it reaches its terminal velocity. Assuming an atmospheric density of 1.3 kg/m^3, and an arrow with a drag coefficient of 1.2, a weight of 0.23 N (200 grains), cross-sectional area of 23.48 mm^2, I calculate a terminal velocity of 112.6 m/s. That's about the same as the initial velocity when shot from a compound bow! One question remains, however: does the arrow have enough time during its descent to reach terminal velocity? That would depend on how high you shot it in the first place. Roughly speaking, though, the faster it was going when it left the bow, the faster it will be going when it reaches the ground.
What will reach its terminal velocity first a penny or an elephant?
Which ever object has the lowest terminal velocity since it will take longer to accelerate to a higher velocity. Galileo showed that dissimilar object fall at similar rates and in the absence of air both objects would fall at an identical rate.
Why can friction make observing newton's first law of motion terminal velocity?
This question does not make sense
If a 75 kg person and a 200 kg crate were launched out of a plane at the same time which one would reach terminal velocity first?
As Galileo demonstrated, acceleration is independent of mass, therefore, they would reach terminal velocity at the same time. This is, of course, ignoring air friction.
Do bubbles reach terminal velocity?
It depends on the type of bubbles. Hydrogen bubbles are often used to visualize aerodynamic flows around models. How you would work out their terminal velocity is by balancing their drag force and buoyancy force. First you would need an estimate of the bubble diameter, somewhere around .025 mm. For water, density of fluid =998 kg/m3 and fluid viscosity = 1.12*10-3 Pa*s FB=density of fluid*volume of bubble*gravity FD=3*pi*fluid viscosity*diameter*velocity of water At the terminal velocity FD=FB, you should have all the other variables, just rearrange to solve for the terminal velocity.
What is the correct spelling for styrofoam?
You got it right the first time. STYROFOAM.
Why do falling objects accelerate at first?
Falling objects accelerate due to the force of gravity acting upon them. As the object falls, the force of gravity pulls it downward, increasing its speed. This acceleration continues until the object reaches terminal velocity or encounters another force counteracting gravity.
What will happen if a parachutist opens its parachute before reaching its terminal velocity?
If a parachutist opens their parachute before reaching terminal velocity, they may experience a sudden jerk as the parachute deploys and slows their descent rapidly. This could potentially cause discomfort or nausea. It is generally recommended to wait until reaching terminal velocity before opening the parachute to ensure a smoother deployment.
What happens to the velocity of a marble as it accelerates down its first hill?
The velocity of the marble increases as it accelerates down its first hill due to the force of gravity. As the marble descends, the gravitational potential energy is converted into kinetic energy, leading to an increase in velocity until it reaches the bottom of the hill.
