Topic: Scalars and Vectors

Question 2 NECO • 2019 • PHYSICS • practical

In a force table experiment, two forces are applied as follows: - Force F₁ = 5.0 N acting at an angle of 30° measured anticlockwise from the positive x‑axis. - Force F₂ = 8.0 N acting at an angle of 120° measured anticlockwise from the positive x‑axis. The table is level and frictionless. The student is required to determine the resultant of the two forces.

Question Parts

( a )

Resolve each force into its horizontal (x) and vertical (y) components, showing the work.

( b )

Using the components obtained in part (a), calculate the magnitude and direction (angle measured anticlockwise from the positive x‑axis) of the resultant force.

( c )

Explain why speed, a scalar quantity, cannot be added vectorially in the same way as the forces above.

( d )

Suggest one precaution that should be observed when using the force table to obtain accurate results.
