A car traveling at a constant speed goes around a sharp curve. Is the car accelerating? Explain.
2 answers:
Acceleration is defined as the rate of change of velocity of any object with time.
Since, speed is kept constant but direction is changed as it goes around the sharp curve and change in the direction results in acceleration as velocity is a vector quantity which depends upon magnitude as well as on direction.
Although, speed of the car is constant, for motion around the sharp curve, the direction is changing; hence the car will have acceleration.
Thus, the car has acceleration because it is changing direction as it goes around the curve.

Answer:ok so When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
