What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?
When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.
What happen to the acceleration of the cart as you decrease the the washers in the pan?
Decreasing washers in the pan decreases mass, so acceleration should increase.
How does net force affect acceleration?
The net force acting on an object is directly proportional to its acceleration, according to Newton's second law of motion. When the net force increases, the acceleration of the object increases as well. Conversely, when the net force decreases, the acceleration of the object decreases.
What is the gradient of acceleration time graph?
The gradient of an acceleration-time graph represents the rate at which the acceleration is changing over time. If the gradient is positive, it indicates an increase in acceleration, while a negative gradient indicates a decrease in acceleration. A horizontal line on the graph would represent a constant acceleration, where the gradient is zero.
What will be the acceleration of a car moving in a uniform acceleration?
The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.
How is acceleration due to gravity be zero in a parachute?
In the case of a parachute, the person and parachute fall at a constant speed once the forces acting on them are balanced. This means that the net acceleration, including gravity, is zero. Gravity is still acting on the person and parachute, but it is balanced by the drag force exerted by the parachute, resulting in a constant speed descent.
Why is the acceleration of gravity the same for all objects regardless of their mass but when 2 people jump from an airplane with the same size parachute the heavier person has greater final velocity?
Acceleration due to gravity is the same ONLY if you assume there is no air resistance. This is definitely not the case if you use a parachute.
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.
When skydiver slows down from 54 meters to 4 meters by opening his parachute If this takes 0.75 seconds what is the magnitude of the skydiver's acceleration?
the magnitude of the skydivers acceleration is zero as he is decelerating by opening his parachute!
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.
What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?
When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.
Does a negative acceleration always mean a decrease in speed?
Not necessarily. Negative acceleration indicates a decrease in velocity, which can either mean a decrease in speed or a change in direction depending on the initial velocity and the direction of the acceleration.
What is the term that describes a decrease in acceleration?
it is still acceleration, but it is negative.
Can a man in a parachute accelerate?
Yes. Acceleration can be positive or negative. When he jumps out of the airplane and is in free fall, he is accelerating in a downward direction, so his acceleration is negative. When he opens his parachute, he accelerates in an upward direction, so his acceleration is positive.
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.
Does air resustance increase or decrease the acceleration of a falling abject?
Decrease.
Can acceleration change with out increase or decrease speed?
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
