How Do Force, Mass, and Direction Affect Acceleration?

Discover the three key factors that influence acceleration: force, mass, and direction of movement.

0 views

Three things that can change acceleration are force, mass, and the direction of movement. According to Newton's Second Law of Motion, acceleration changes when a force acts on an object (F=ma). Increasing or decreasing the force applied or altering the mass of the object will impact its acceleration. Additionally, changing the direction of the applied force will also result in a change in acceleration.

FAQs & Answers

  1. What is acceleration according to Newton's Second Law? Acceleration is defined as the rate of change of velocity of an object and is directly proportional to the net force acting on it and inversely proportional to its mass.
  2. How can increasing mass affect acceleration? Increasing the mass of an object while keeping the force constant will result in a decrease in acceleration, as described by the equation F=ma.
  3. What role does direction play in acceleration? Changing the direction of the applied force can lead to a change in acceleration, as acceleration is a vector quantity that depends on both magnitude and direction.
  4. What are some real-world examples of changing acceleration? Examples include vehicles accelerating when accelerating or braking and athletes changing speed or direction while running.
