motion in one dimension

Front

What is the formula to calculate time when distance and speed are known?

Back

Time = Distance / Speed

Front

Define displacement in the context of motion.

Back

Displacement is the shortest distance from the initial to the final position of an object, measured in a straight line.

Front

What does a negative acceleration indicate about an object's motion?

Back

Negative acceleration indicates that the object is slowing down.

Front

What does a graph parallel to the time axis in a velocity-time graph represent?

Back

It represents zero acceleration.

Front

How do you calculate average acceleration?

Back

Average acceleration = (Final velocity - Initial velocity) / Time taken.

Front

If an object moves with a constant velocity, what can be said about its acceleration?

Back

The acceleration is zero.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the starting point to the ending point.

Front

What is the unit of acceleration in the SI system?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car travels 300 km in 4 hours, what is its average speed?

Back

Average speed = Distance / Time = 300 km / 4 h = 75 km/h.

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed.
