CP Physics A Module 03

Front

What is the direction of the resultant displacement when a vector is 27 degrees, North of West?

Back

The resultant displacement is directed 27 degrees, North of West.

Front

What is the horizontal component of a displacement of 30 km in practice B?

Back

The horizontal component is 30 km, West.

Front

What is the vertical component of a displacement of 40 km in practice B?

Back

The vertical component is 40 km, South.

Front

Define a vector in physics.

Back

A vector is a quantity that has both direction and magnitude.

Front

What is the resultant displacement of a car that travels 90 meters due North and then 40 meters due South?

Back

The resultant displacement is 50 meters, North.

Front

What is the formula to calculate the resultant displacement of two vectors?

Back

The resultant displacement can be calculated using the Pythagorean theorem if the vectors are perpendicular: R = √(A² + B²).

Front

What does it mean for a vector to have a magnitude of 0?

Back

A vector with a magnitude of 0 has no direction and represents no displacement.

Front

How do you determine the direction of a resultant vector?

Back

The direction of a resultant vector can be determined using trigonometric functions (sine, cosine) based on the components.

Front

What is the significance of the angle in vector displacement?

Back

The angle indicates the direction of the vector relative to a reference direction (e.g., North, East).

Front

What is the difference between scalar and vector quantities?

Back

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