Sample problems of uniform acceleration ( physics)class 11 ?
Understanding Uniform Acceleration
Uniform acceleration occurs when an object's velocity changes at a constant rate. This concept is crucial in understanding motion in physics. Here are some sample problems to illustrate the concept:
Sample Problem 1: Car Accelerating from Rest
A car starts from rest and accelerates uniformly at a rate of 2 m/s².
Sample Problem 2: Ball Thrown Upwards
A ball is thrown vertically upwards with an initial velocity of 15 m/s.
Conclusion
These problems demonstrate how to apply the equations of motion for objects undergoing uniform acceleration. Understanding these principles is essential for solving various physics problems related to motion.
Uniform acceleration occurs when an object's velocity changes at a constant rate. This concept is crucial in understanding motion in physics. Here are some sample problems to illustrate the concept:
Sample Problem 1: Car Accelerating from Rest
A car starts from rest and accelerates uniformly at a rate of 2 m/s².
- Find the velocity after 5 seconds.
- Use the formula: v = u + at
- Here, u = 0 m/s, a = 2 m/s², t = 5 s
- Calculation: v = 0 + (2)(5) = 10 m/s - Calculate the distance covered in that time.
- Use the formula: s = ut + (1/2)at²
- Calculation: s = (0)(5) + (1/2)(2)(5²) = 25 m
Sample Problem 2: Ball Thrown Upwards
A ball is thrown vertically upwards with an initial velocity of 15 m/s.
- Determine the maximum height reached.
- At maximum height, final velocity (v) = 0 m/s
- Use the formula: v² = u² + 2as (where a is the acceleration due to gravity, -9.8 m/s²)
- Calculation: 0 = (15)² + 2(-9.8)s
- Solve for s: s = 11.47 m - Calculate the time taken to reach the maximum height.
- Use the formula: v = u + at
- Calculation: 0 = 15 - 9.8t, t = 1.53 seconds
Conclusion
These problems demonstrate how to apply the equations of motion for objects undergoing uniform acceleration. Understanding these principles is essential for solving various physics problems related to motion.
