Acceleration and deceleration are caused by changes in an object's velocity. Acceleration occurs when an object speeds up due to applied force, like pressing a car's gas pedal. Deceleration happens when an object slows down, often due to braking or friction.

FAQs & Answers

  1. What is the difference between acceleration and deceleration? Acceleration refers to an increase in an object's velocity, while deceleration means a decrease or slowing down of velocity, often due to opposing forces like friction or braking.
  2. What causes acceleration in a moving object? Acceleration is caused by an applied force that increases the velocity of an object, such as pressing a car's gas pedal.
  3. How does friction contribute to deceleration? Friction opposes motion and causes deceleration by slowing down an object's velocity when forces like brakes are applied.
  4. Can acceleration and deceleration occur without external forces? No, acceleration and deceleration require external forces to change an object's velocity according to Newton's laws of motion.
