Skydiving Physics Concepts

The video tutorial discusses the physics of skydiving, focusing on Newton's laws of motion. It explains how a skydiver maintains motion with the airplane due to Newton's first law. The forces acting on a skydiver, such as gravity and air resistance, are explored, along with the concept of terminal velocity. The tutorial also compares the sensation of weightlessness in skydiving to scuba diving.

Why doesn't a skydiver hit the plane's stabilizer when jumping out?

• The stabilizer is too high to reach.

• The skydiver is moving at the same speed as the plane.

• The skydiver is pushed away by the wind.

• The skydiver jumps upwards.

What is the primary force acting on a skydiver before the parachute is deployed?

• Magnetic force

• Air resistance

• Gravity

• Friction

How does air resistance affect a skydiver after the parachute opens?

• It makes the skydiver move upwards.

• It increases the skydiver's speed.

• It decreases the skydiver's speed.

• It has no effect on the skydiver's speed.

What happens to the net force on a skydiver when air resistance equals gravity?

• The skydiver stops moving.

• The skydiver accelerates downwards.

• The skydiver moves at a constant speed.

• The skydiver accelerates upwards.

What is terminal velocity?

• The speed at which a skydiver moves upwards.

• The speed at which a skydiver starts falling.

• The maximum speed a skydiver reaches when forces are balanced.

• The speed at which a skydiver stops falling.

How does a parachute affect terminal velocity?

• It decreases terminal velocity.

• It increases terminal velocity.

• It has no effect on terminal velocity.

• It makes terminal velocity infinite.

What is the effect of air resistance on a skydiver's speed?

• It decreases the speed to zero.

• It balances with gravity to maintain constant speed.

• It increases the speed indefinitely.

• It has no effect on speed.

What does feeling weightless while skydiving compare to?

• Flying in an airplane.

• Standing on solid ground.

• Floating in water with neutral buoyancy.

• Being in a vacuum.

Why might a scuba diver feel weightless?

• Because they are in space.

• Due to neutral buoyancy.

• Because they are not moving.

• Due to the absence of gravity.

What is the main difference between feeling weightless in space and while skydiving?

• Space has no gravity.

• Skydiving involves air resistance.

• Space is colder.

• Skydiving is faster.
