Physics-Force and motion

• What happens to an object's velocity when it moves along a circular path?

  Its velocity is always changing
• How does the speed of an object in circular motion behave?

  It has constant speed but changing velocity
• Why is an object moving in a circle not in equilibrium?

  It has a resultant force acting on it
• What is the name of the force that keeps an object moving in a circle?

  Centripetal force
• How is centripetal force defined?

  Resultant perpendicular force toward the center
• What is required to keep a body in uniform circular motion?

  A resultant perpendicular force toward the center
• In what direction does centripetal force act?

  Towards the center of the circle
• How does centripetal force relate to the direction of travel?

  It is perpendicular to the direction of travel
• What is the effect of centripetal force on an object in circular motion?

  It keeps the object moving in a circle
