What Two Factors Cause Acceleration in Physics?
Learn the two key factors that cause acceleration: changes in speed or direction, and how Newton's second law explains this concept.
0 views
Acceleration occurs due to changes in speed or direction. Speeding up, slowing down, or changing the direction of an object's motion results in acceleration. In physics, these changes are often described by Newton’s second law, where acceleration depends on the force applied and the object’s mass.
FAQs & Answers
- What causes acceleration in an object? Acceleration occurs when there is a change in speed or direction of an object's motion.
- How does Newton's second law relate to acceleration? Newton's second law states that acceleration depends on the force applied to an object and its mass.
- Can an object accelerate if its speed remains constant? Yes, an object can accelerate by changing direction even if its speed stays the same.
