Answer (1)
Part 1: Conceptual Questions1. Define uniformly accelerated motion and give two real-life examples.Uniformly accelerated motion occurs when an object's velocity changes at a constant rate over time.Examples:A car accelerating at a constant rate when moving from rest.A ball rolling down a smooth incline, increasing speed at a steady rate.2. What is the difference between uniform motion and uniformly accelerated motion?Uniform Motion: The object moves at a constant velocity (no acceleration).Uniformly Accelerated Motion: The object's velocity changes at a constant rate.3. How does acceleration affect the velocity of an object over time?Positive acceleration → Velocity increases over time.Negative acceleration (deceleration) → Velocity decreases over time.If acceleration is zero, velocity remains constant.4. What is the acceleration of an object in free fall near Earth's surface? What is its value?An object in free fall accelerates due to gravity.The acceleration due to gravity on Earth is 9.8 m/s² (downward).5. Describe how the velocity-time graph of an object in uniformly accelerated motion looks.It is a straight line with a constant slope.If acceleration is positive, the line slopes upward.If acceleration is negative (deceleration), the line slopes downward.
