Precision refers to how close the measured value is to the accepted value.

Velocity is a scalar quantity because it only has magnitude.

If two vectors of 7 m east and 9 m east are added, then the answer is 16 m.

For a right triangle with sides 8 m and 15 m, the resultant is 17 m.

Sine law is only used when the triangle is a right triangle.

Two perpendicular vectors, 9 m east and 12 m north, have a resultant of 15 m.

To solve for the direction of the resultant vector using the component method, we should use tangent function.

The dot product of two parallel vectors is maximum.

The magnitude of the cross product depends on the cosine of the angle between the two vectors.

Displacement can be equal to distance.

A runner covers 600 m in 75 s. Average speed is 8.0 m/s.

An object changes velocity from 4 m/s to 16 m/s in 6 s. Acceleration is 2.0 m/s².

Deceleration always means the velocity is negative.

Kinematic equations are valid only when acceleration is constant.

A distance is measured as 3.6 × 10³ mm. Express this in meters.
