Q2)velocity formula is = displacement/time T/F?
- True
Answer:
Gravity and
Air resistance
Explanation:
The two forces acting on a skydiver are gravitational force and air resistance.
Gravitational force is a force that tends to pull all massive bodies towards the center of the earth. It works on all bodies that has mass. The larger or bigger the mass, the more the pull of gravity on the body.
Air resistance is the drag of air on a body as it passes to it. It is resisting force.
- When a sky diver jumps out of a plane, he/she encounters both gravity and air resistance.
- It soon balances both force and attain terminal velocity.
- Air resistance is a frictional force that opposes motion.
- This frictional force pushes in the opposite direction of motion
- Motion direction is downward due to the celerity caused by gravity.
Answer:
The person on the truck would have the same speed as that of the truck. Also, before the ball is thrown, the ball would have the speed as that of the truck.
It is possible for a person standing at the side of the road to view the falling straight down. This would be possible if the ball is thrown backwards with the same magnitude of velocity as that of truck.
To the person on the truck, the ball would appear to have forward motion with the speed of the truck.
