Important Questions on Motion in a Plane - CBSE Class 11
1. Define displacement and differentiate it from distance.
2. Explain the concept of vector addition. Derive the expression for the resultant of two vectors using the parallelogram law of vector addition.
3. What are the conditions for uniform circular motion? Derive the relation between centripetal acceleration and velocity.
4. A boat is moving at 5 m/s in still water. If the river current flows at 3 m/s, calculate the resultant velocity of the boat if it moves perpendicular to the current.
5. Define the term "angular velocity". How is it related to linear velocity?
6. A projectile is fired with an initial velocity of 30 m/s at an angle of 45° to the horizontal. Calculate the maximum height and time of flight.
7. A car travels along a circular track of radius 50 m at a speed of 10 m/s. Calculate the centripetal force acting on the car if its mass is 800 kg.
8. What is the range of a projectile? Derive an expression for the same in terms of its initial velocity and angle of projection.
9. Explain the difference between scalar and vector quantities, and provide examples for both.
10. A ball is thrown with a velocity of 20 m/s at an angle of 60° to the horizontal. Calculate the horizontal range and the maximum height attained by the ball.
