Study Notes
Linear Motion
- A particle moves along a straight line with an acceleration of 2 m/s^2.
- If the initial velocity is 5 m/s, the velocity after 4 seconds can be calculated.
- Force and mass are related to acceleration, but not mentioned in this scenario.
Rotational Motion
- A rigid body rotates about a fixed axis with an angular velocity of 3 rad/s.
- If the angular acceleration is 2 rad/s^2, the angular velocity after 2 seconds can be calculated.
- Angular displacement is related to angular velocity, but not mentioned in this scenario.
Force and Acceleration
- A force of 50 N is applied to a body of mass 10 kg.
- The resulting acceleration can be calculated using the force and mass.
Rotational Kinematics
- A rigid body rotates about a fixed axis with an angular displacement of 2 rad.
- If the angular velocity is 4 rad/s, the time elapsed can be calculated.
Circular Motion
- A particle moves in a circular path with a radius of 2 m.
- If the angular velocity is 5 rad/s, the linear velocity can be calculated.
- The radius of the circular path is 2 m.
