Does it take the same amount of force to start something as it does to keep it moving?
No, it typically takes more force to start something moving from rest due to overcoming static friction. Once in motion, the force required to keep it moving is generally less, due to kinetic friction being lower than static friction.
What measures how fast air particles are moving?
Temperature measures how fast air particles are moving. Higher temperatures mean faster-moving particles, while lower temperatures mean slower-moving particles.
Did you exert a force to keep the stone moving in a circle?
Yes, to keep an object moving in a circle, a force must be exerted towards the center of the circle. This is known as centripetal force.
Is it true that to keep an object moving a force must be apllied?
Yes, according to Newton's first law of motion, an object will remain in its state of motion (either at rest or moving at a constant velocity) unless acted upon by an external force. In order to keep an object moving, a force must be continuously applied to overcome any friction or resistance that might slow it down.
Why doesn't an object keep moving?
An object will keep moving if no external force acts upon it to stop or change its motion. In the absence of friction or resistance, an object in motion will continue moving at a constant velocity due to its inertia.
