CA Review 4

Front

What is constant speed?

Back

Constant speed means an object is moving at the same rate over time, covering equal distances in equal intervals.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity. It can be positive (speeding up) or negative (slowing down).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t).

Front

What does a flat line on a distance-time graph represent?

Back

A flat line indicates that the object is not moving; it is stationary.

Front

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

Back

A steep slope indicates a high speed; the steeper the slope, the faster the object is moving.

Front

What is the unit of speed?

Back

The unit of speed is meters per second (m/s).

Front

If an object travels 300 meters in 60 seconds, what is its speed?

Back

Speed = Distance / Time = 300 meters / 60 seconds = 5 m/s.

Front

What does it mean if an object is uniformly accelerated?

Back

Uniform acceleration means the object is accelerating at a constant rate.

Front

What is the average speed of a car that travels 20 meters in 10 seconds?

Back

Average speed = Distance / Time = 20 meters / 10 seconds = 2 m/s.
