What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating average speed?

Back

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 speed and direction.

Front

What does the slope of a distance-time graph represent?

Back

The slope of a distance-time graph represents speed.

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.

Front

If an object is moving at a constant speed, what is its acceleration?

Back

The acceleration is 0 m/s².

Front

How do you calculate the total distance traveled if an object moves in two segments?

Back

Total distance = Distance of segment 1 + Distance of segment 2.

Front

What is the unit of acceleration?

Back

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

Front

What is the average speed of a car that travels 200 m in 50 seconds and then 125 m in 25 seconds?

Back

Average speed = (200 m + 125 m) / (50 s + 25 s) = 4.33 m/s.

Front

What is the definition of uniform motion?

Back

Uniform motion is when an object moves at a constant speed in a straight line.
