Question
Explain why an object can accelerate even if its speed remains constant.
Answer
An object can accelerate if its direction changes, even if its speed remains constant. This is because acceleration is defined as the rate of change of velocity, which includes changes in direction.
Explanation
This question assesses the understanding of the concept of acceleration and velocity. It challenges students to apply their knowledge of motion to explain how direction affects acceleration, reinforcing the distinction between speed and velocity.
Common mistake
Rearranging the Equation
Students often struggle to correctly rearrange the equation v^2 - u^2 = 2as, leading to incorrect calculations of acceleration, distance, or final velocity.
Practice isolating each variable step-by-step, ensuring to apply inverse operations correctly. Use examples to reinforce the process of rearranging equations.
