What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up), negative (slowing down), or zero (constant speed).

What does a velocity vs. time graph represent?

Back

A velocity vs. time graph shows how the velocity of an object changes over time. The slope of the graph indicates acceleration.

Front

How do you calculate distance when speed and time are known?

Back

Distance = Speed × Time.

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, including direction.

Front

What does a flat line on a velocity vs. time graph indicate?

Back

A flat line indicates that the object is moving at a constant velocity, meaning there is zero acceleration.

Front

How do you determine the speed of an object from a distance vs. time graph?

Back

The speed is determined by calculating the slope of the line on the graph, which is the change in distance divided by the change in time.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What does a negative slope on a velocity vs. time graph indicate?

Back

A negative slope indicates that the object is decelerating or slowing down.

Front

If an object travels 100 m in 4 seconds, what is its speed?

Back

Speed = Distance / Time = 100 m / 4 s = 25 m/s.

What is uniform motion?

Back

Uniform motion occurs when an object travels equal distances in equal intervals of time, indicating constant speed.
