If the centrialfugal force is equal to the gravity, than the apple should be staying in the same spot at the tree. If the centrialfugal force needed is greater than gravity, then the apple would not stay in the free and would flying away from the earth.
Q. Why do two bodies not attract each other?
According to the laws of gravitation force, all masses attract each other. the greater the masses, the stronger the pull. the closer the masses, the stronger the pull.

Q. What causes items to attract?
Electric charge is a physical property of particles or objects. It causes them to attract or repel each other without touching. Positive and negative particles attract each other. Particles with the same charge repel each other.

Q. What would happen if there was no gravity for 5 seconds?
If our planet were to lose gravity for even five seconds, it would spell the end of life on Earth as we know it. Gravity pulls objects toward one another. The more massive an object is, the stronger its gravitational pull. Without gravity, humans and other objects would become weightless.
Q. Can we walk if there is no friction?
No, we can’t walk if there is no friction because when we walk, we push the ground with our feet and friction pushes in the opposite direction then we move forward.
Q. What will happen if friction disappears from the earth give at least 5 examples?
1: You will not be able to write. 2: No riding cycle, bike and not even a car or bus. 3: No machines in companies and so no mechanics. 4: You would have not been able to sit, walk, run or dance.
Q. What are three everyday activities you couldn’t do without friction?
Walking. Driving a car. Staying in your seat. Operating a mouse and a computer….
- Sneezing and still staying in the same place.
- Belt-pulley drive.
- Ease in normal walking.
- Holding a bottle for drinking water.
Q. Which activities would not be possible in the absence of friction?
Answer. Answer: Walking, writng, driving, objects to be piled etc..
Q. Which case has least friction?
Glass has comparatively a better polished and regular smooth surface. So it has least friction.
Q. Which case is desirable friction?
Friction is desirable in braking of a vehicle. As brakes are applied, friction between brake shoes and tyres opposes rotation of tyres and hence, forces it to stop.
