Why did the ball roll when laid on the floor? because the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball’s bottom surface(ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll. […]
Which is more elastic glass or steel?
Which is more elastic glass or steel? The Coefficient of elasticity of glass is between 50 and 90; the Coefficient of elasticity of steel is 210; the Coefficient of elasticity of Copper is 120. Therefore, the rubber is more elastic than glass and glass is more elastic than copper and copper is more elastic than […]
Is it possible for a car to move at constant speed and be accelerating?
Is it possible for a car to move at constant speed and be accelerating? The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity […]

What will happen if the air pressure increases?
What will happen if the air pressure increases? For example, if air pressure increases, the temperature must increase. If air pressure decreases, the temperature decreases. It also explains why air gets colder at higher altitudes, where pressure is lower. Which prediction is most likely when the air pressure increases? If air pressure rises, a high […]
