CP Physics A Module 02

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction. It is a vector quantity.

Front

Can velocity be negative?

Back

Yes, velocity can be negative, indicating that an object is moving in the opposite direction.

Front

What is the formula to calculate displacement when given initial velocity, acceleration, and time?

Back

Displacement (s) = ut + 0.5at², where u is the initial velocity, a is the acceleration, and t is the time.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity.

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 difference between scalar and vector quantities?

Back

Scalar quantities have only magnitude (e.g., speed, distance), while vector quantities have both magnitude and direction (e.g., velocity, displacement).

Front

What is constant acceleration?

Back

Constant acceleration means that the rate of change of velocity is constant over time.

Front

If an object starts from rest and accelerates at 2.3 m/s², how far will it travel in 9.3 seconds?

Back

Using the formula s = ut + 0.5at², the distance traveled is 0.5 * 2.3 * (9.3)² = 100 m.

Front

What is the significance of the direction in vector quantities?

Back

The direction in vector quantities is crucial as it determines the actual path and position of the object in space.

Front

What is the relationship between distance and displacement?

Back

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