FAQs on Acceleration Video Lecture - Physics Class 11 - NEET

1. What is acceleration in physics?
Ans.Acceleration is defined as the rate of change of velocity of an object with respect to time. It can be calculated using the formula \( a = \frac{\Delta v}{\Delta t} \), where \( \Delta v \) is the change in velocity and \( \Delta t \) is the time taken for that change.
2. What are the different types of acceleration?
Ans.There are primarily three types of acceleration: uniform acceleration, where the velocity changes at a constant rate; non-uniform acceleration, where the velocity changes at varying rates; and instantaneous acceleration, which measures the acceleration of an object at a specific moment in time.
3. How do you calculate acceleration?
Ans.Acceleration can be calculated using the formula \( a = \frac{v_f - v_i}{t} \), where \( v_f \) is the final velocity, \( v_i \) is the initial velocity, and \( t \) is the time taken for the change in velocity. This gives the average acceleration over that time period.
4. What units are used to measure acceleration?
Ans.Acceleration is typically measured in meters per second squared (m/s²) in the International System of Units (SI). This unit indicates how much the velocity of an object changes per second for every second of acceleration.
5. What is the difference between linear and angular acceleration?
Ans.Linear acceleration refers to the change in velocity of an object moving along a straight path, while angular acceleration refers to the rate of change of angular velocity of an object rotating around a fixed point. Linear acceleration is measured in m/s², whereas angular acceleration is measured in radians per second squared (rad/s²).
