Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
What forces acts against gravity?
air resistance. like dropping a sheet of paper, it flops everywhere because air is trying to keep it up and gravity is pulling it down. Or a feather, air slows it down as it falls.
How is gravity related to terminal velocity?
Based on the 9th grade book of Physical Science... Gravity is a force that acts between two masses, and Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. So, gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration... which ties together terminal velocity.
What is the net force acting on a falling 1-kg rm kg ball if it encounters 2 N rm N of air resistance?
Since gravity attracts the ball downward, and air resistance acts upwards (assuming that it falls straight down), you need to subtract the force of gravity (i.e., the weight) minus the air resistance.
What part air resistance plays in gravity?
i think air resistance slows down the object that gravity is pulling towards it
What are 3 forces that act on an object from a catapult?
The potential energy of the elasticity of the catapult material, air resistance, gravity.
What force acts on a object?
The forces acting on a falling body are gravity and air resistance.
What force is there on free falling body neglecting air friction?
The force of gravity is the primary acting force. Air resistance acts in the opposite direction.

When no air resistance acts on a nicely tossed basketball its acceleration is what?
It doesn't matter whether the object is a basketball or something else. If there is no air resistance, the acceleration due to gravity is 9.8 meters/second2, in the downward direction.
How is air resistance related to a catapult?
the ball or whatever object that is thrown has air resistance so it makes it go farther or slower and that's how its related
How great is the air resistance that acts on a 10-N sack that falls in air at constant velocity?
constant velocity= no acceleration and no net force Assuming that there are no other forces acting on the sack (besides gravity and air resistance) this means that the force of air friction equals the weight of the object, so that the air resistance is 10N acting upward exactly balancing the force of gravity acting down
