Uniform and Non-Uniform Motion Puzzles
1. What is uniform motion?
Hint: Does speed change over time?Uniform motion occurs when an object moves equal distances in equal time intervals without changing speed.
2. What is non-uniform motion?
Hint: Does speed remain constant?Non-uniform motion occurs when an object covers unequal distances in equal time intervals, meaning its speed is changing.
3. A car moves at a constant speed of 20 m/s for 10 minutes. Is this uniform or non-uniform motion?
Hint: Is speed changing?It is uniform motion because the speed remains constant.
4. A train moves at 30 m/s, slows down to 10 m/s, then stops. Is this uniform or non-uniform motion?
Hint: Is speed decreasing?It is non-uniform motion because speed is changing.
5. A ball falls freely under gravity. Is this uniform or non-uniform motion?
Hint: Does acceleration remain constant?Non-uniform motion because the velocity keeps increasing due to acceleration due to gravity.
6. How does the displacement-time graph look for uniform motion?
Hint: Is it a straight or curved line?A straight line with a constant slope.
7. How does the displacement-time graph look for non-uniform motion?
Hint: Is the slope changing?A curved line, as the speed is not constant.
8. If an object moves with a constant velocity, what is its acceleration?
Hint: Does velocity change?Acceleration is zero because velocity remains constant.
9. A cyclist moves 5m in the first second, 7m in the next second, and 10m in the third second. Is this uniform or non-uniform motion?
Hint: Is the distance covered in equal time intervals constant?Non-uniform motion because the distance covered per second is increasing.
10. What does the velocity-time graph of uniform acceleration look like?
Hint: How does velocity change with time?A straight line with a positive slope.
