Physics - Unit 1 Review

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the starting point to the ending point, including direction.

Front

Define average speed.

Back

Average speed is the total distance traveled divided by the total time taken.

Front

What is velocity?

Back

Velocity is the rate of change of displacement with respect to time, and it includes both speed and direction.

Front

Can an object have a high velocity and a low speed?

Back

No, velocity is dependent on speed and direction; if speed is low, velocity cannot be high.

Front

What does it mean if an object has an average speed of 0 m/s?

Back

It means the object has returned to its starting point, resulting in no net displacement.

Front

How do you calculate displacement?

Back

Displacement is calculated as the final position minus the initial position.

Front

What is the formula for average velocity?

Back

Average velocity = (final position - initial position) / total time.

Front

If a car travels 100 m north and then 100 m south, what is its displacement?

Back

The displacement is 0 m, as the car returns to its starting point.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it differentiates between different velocities even if the speed is the same.

Front

Explain the concept of instantaneous speed.

Back

Instantaneous speed is the speed of an object at a specific moment in time.
