What is One Dimensional Kinematics?

Back

One Dimensional Kinematics is the branch of mechanics that deals with the motion of objects along a straight line, focusing on concepts such as displacement, velocity, acceleration, and time.

Front

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object. It is defined as the shortest distance from the initial to the final position, along with the direction.

What is the formula for calculating average speed?

Back

Average speed is calculated using the formula: Average Speed = Total Distance / Total Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both the speed of the object and the direction of its motion.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time. It can be positive (speeding up) or negative (slowing down).

Front

What is the standard SI unit for acceleration?

Back

The standard SI unit for acceleration is meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

Acceleration can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for calculating distance when acceleration is constant?

Back

The formula for calculating distance (d) when acceleration is constant is: d = v_i * t + 0.5 * a * t², where v_i is the initial velocity, a is acceleration, and t is time.

Front

What is the significance of human reaction time in kinematics?

Back

Human reaction time is significant in kinematics as it affects the distance an object falls or moves before a person can respond, impacting calculations in motion scenarios.

Front

What is the formula for calculating final velocity?

Back

Final velocity (v_f) can be calculated using the formula: v_f = v_i + a * t, where v_i is the initial velocity, a is acceleration, and t is time.
