What else can I help you with?
Does air resistance increase or decrease the acceleration of a falling obect?
Well, the more the air resistance, the lower the acceleration.
What objects increase air resistance?
Objects that increase air resistance include large surface area objects (such as flags or parachutes), rough or uneven surfaces, and objects with irregular shapes (such as a car spoiler or a parachute harness). These objects create more friction with the air as they move, resulting in higher air resistance.
What is ways to decrease air resistance?
To decrease air resistance, you can streamline the shape of the object moving through the air, reduce its surface area exposed to the air, and minimize any protruding or irregular features that would create drag. Additionally, you can increase the object's speed to help reduce the impact of air resistance.
What cause acceleration to decrease?
Acceleration can decrease due to friction, air resistance, or an opposing force acting in the opposite direction to the motion. An increase in mass or a decrease in the force applied can also cause acceleration to decrease.
Does air resistance increase or decrease the acceleration of a falling leaf from a tree?
Air resistance decreases the acceleration of a falling leaf from a tree. As the leaf falls, air resistance opposes its motion, slowing it down. This results in a lower acceleration compared to if the leaf were falling in a vacuum with no air resistance.
How can you increase or decrease acceleration?
To increase acceleration, you can apply more force or reduce resistance. This can be achieved by pushing harder on the gas pedal in a car or reducing air resistance by changing body position while skiing. To decrease acceleration, you can apply less force or increase resistance, such as by letting off the gas pedal in a car or increasing air resistance by opening a parachute while skydiving.
When the air rises does it increase or decrease?
When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
What are two ways to increase air resistance of an object?
Increasing the surface area of the object, such as by adding flaps or a parachute, can increase air resistance. Additionally, increasing the object's speed will also increase the air resistance acting on it.
Does air resustance increase or decrease the acceleration of a falling abject?
Decrease.
How does changing the shape of an object affect the friction and air resistance?
Changing the shape of an object can affect friction and air resistance. For friction, the surface area in contact with another surface can increase or decrease, altering the friction force. For air resistance, a more streamlined shape will experience less resistance compared to a less streamlined shape due to differences in how air flows around the object.
What causes speed to decrease?
Speed can decrease due to forces like friction, air resistance, or gravity acting in the opposite direction to the motion. Additionally, factors like an increase in mass or a change in the surface conditions can also cause speed to decrease.
What happens to drag as altitude increase?
As altitude increases, the density of the air decreases, resulting in a decrease in drag on an object moving through the air. This is because there are fewer air molecules to create resistance against the object's motion.
