What happens when you throw a ball up?
When we throw a ball upwards, its speed retards gradually.
This is because the earth produces a gravitational force which brings down everything that goes up.
So when a ball is thrown upward the gravity applies force to bring it down which decreases its speed of going up..
Can an astronaut throw a ball back to Earth?
Can an astronaut throw a ball to the Earth? The answer is Yes, and No. … The extra velocity you gave it with your throw is in the same direction as before, but because of the orbit, that direction now points away from the Earth and directly back towards the ISS. So it doesn’t keep going towards the Earth.
How do you throw a ball as far as possible?
ProcedureThrow your ball as hard as you can, relatively straight forward at a “shallow” angle—as parallel to the ground as you can. … Have your helper mark where the ball lands (for example, with a rock).Repeat the throw at that angle two more times.More items…•
Is there friction in space?
Yes, when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn’t depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.
Would a boomerang work in space?
Broadbent told Universe Today that a boomerang would not work in the vacuum of space. … The uneven force caused by the difference in speed between the three wings (two wings on a regular boomerang) applies a constant force which forces the boomerang to turn.
What happens if you throw an object in space?
In deep space, far enough away from large objects like stars and planets that gravity may be neglected, a thrown ball will travel in a straight line and the person throwing the ball will also travel in a straight line in the opposite direction. … The lighter object moving faster.
How fast can you throw a baseball in space?
Watch NASA Astronauts Throw a 17,500 MPH Fastball.
Can you run faster on the moon?
And, according to the study they published today in the Journal of Experimental Biology, humans can run a lot faster in lunar gravity than anyone ever expected. … There, the astronauts were asked to run on a treadmill during 20 second-long dips at lunar gravity.
Can you accelerate forever?
You can accelerate forever, and because of relativity, you will never reach c, so you will in fact have infinite acceleration. In the real universe, this is not possible, because the mass of the universe is finite.
Why does a ball thrown vertically upwards in a moving train come back to the thrower hand?
Due to inertia of motion, as long as the ball stays in air, both the person and the ball move in the same direction which cause the ball to fall back to the thrower’s hand.
What happens if you throw a ball in a car?
When a person throws a ball up in a moving vehicle, say, a train, the ball does come straight back to thrower as though the train were at rest. … So if the train moves with a constant velocity, the ball will exactly return to the thrower.
Can you be still in space?
On the other hand, an object can be standstill in a reference to another object, despite of the fact if both are in motion, orbiting a larger objects or simply flying free. So, the answer is YES always when it is in reference to another space body. Otherwise, there is no such thing as stand still in space.
When a ball is thrown inside a moving bus?
Solution. The kinetic energy of a ball thrown inside a moving bus depends on the speed of the bus because the kinetic energy is directly proportional to the square of the speed of the moving ball. The speed of the bus adds up to the speed with which the ball is thrown inside the bus.
Can an object stop in space?
Space ships do not stop when they run out of fuel. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.
When we throw a ball upward what happens to its speed?
When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball s motion. Its acceleration is -9.8 m/s^2 at the very top.
What does space smell like?
“Space,” astronaut Tony Antonelli has said, “definitely has a smell that’s different than anything else.” Space, three-time spacewalker Thomas Jones has put it, “carries a distinct odor of ozone, a faint acrid smell.” Space, Jones elaborated, smells a little like gunpowder. It is “sulfurous.”
Do things accelerate in space?
The object will continue to travel due to no other force being applied to it once it has left your, travelling at a constant speed. … An object thrown in space will move according to the forces on it in space. For instance, if you threw it in space near the Earth, it would accelerate due to the Earth’s gravity.
How fast would you have to throw a ball to put it in low Earth orbit?
How fast does the baseball need to travel to never hit the ground? The answer is called the circular velocity, and at the surface of Earth (give or take 100 m) the answer is about 8 kilometers per second (km/s). To compare this with speeds you are used to: 1 km/s = 3600 km/hour = about 2300 miles per hour!
Can astronaut fall to earth?
Short answer: The astronaut will orbit the planet and eventually plummet to Earth, only to burn up during re-entry* (*some conditions apply).
Can a bird fly in a moving car?
Yes, a bird can fly in a car. … In the car, you would actually have no idea the car is moving. You will feel no bumpiness or getting pushed into the back of your seat. The air inside would be just as still relative to the car as air in your room is, relative to your room.
When we throw a ball upward it comes down why?
The acceleration due to earth’s gravity, “g” has a value of 9.81 m/s^2. When the ball is thrown up, it is going against the earth’s gravitational field and so, the earth’s gravitational force pulls it back down, accelerating it downwards.
