Understanding One-Dimensional Kinematics

Front

What is the difference between displacement and distance?

Back

Displacement is the shortest distance with direction, while distance is the total path length without direction.

Front

If a car travels 100 meters east and then 100 meters west, what is its displacement?

Back

0 meters

Front

Define speed and how it differs from velocity.

Back

Speed is a scalar quantity measuring distance over time, while velocity is a vector quantity that includes direction.

Front

A runner completes a 400-meter lap in 50 seconds. What is their average speed?

Back

8 meters per second

Front

What is the formula for calculating average velocity?

Back

Average Velocity = Total Displacement / Total Time

Front

If an object moves in a straight line and its position changes from 5 m to 15 m in 2 seconds, what is its average velocity?

Back

5 m/s

Front

Define acceleration in the context of one-dimensional motion.

Back

Acceleration is the rate of change of velocity in one-dimensional motion.

Front

If a car's velocity changes from 20 m/s to 50 m/s in 5 seconds, what is its acceleration?

Back

6 m/s²

Front

What is the formula for calculating acceleration?

Back

a = (v_f - v_i) / t

Front

Explain the difference between uniform and non-uniform acceleration.

Back

Uniform acceleration has constant acceleration, while non-uniform acceleration has varying acceleration.
