What instrument is used to measure the instantaneous speed of a vehicle?

Back

Speedometer

Front

What type of motion is a boy experiencing on a merry-go-round moving at a constant speed of 10 m/s?

Back

Accelerated motion

Front

If a worker travels 40 km to work and 10 km back home, what is the total displacement of the worker?

Back

30 km

Front

What does it mean that acceleration is a vector quantity?

Back

It can be positive, negative, or zero.

Front

How is velocity defined in terms of displacement?

Back

Velocity is defined as displacement per unit 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 speed and direction.

Front

What is the formula for calculating average speed?

Back

Average speed = Total distance / Total time.

Front

What is the relationship between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position.

Front

What is uniform motion?

Back

Uniform motion occurs when an object covers equal distances in equal intervals of time.

Front

What is the formula for acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / Time taken.
