LU 2: Kinematics of Linear Motion

The magnitude of displacement is determined through PYTHAGOREAN THEOREM while the direction of displacement is calculated via TRIGONOMETRY FORMULAS.

• FALSE

• TRUE

The gradient (slope) of displacement-time (s-t) graph represents the VELOCITY.

• TRUE

• FALSE

Area under the acceleration-time (a-t) graph represents NOTHING.

• TRUE

• FALSE

Answer explanation

Area under the acceleration-time (a-t) graph represents VELOCITY.

Which of the following kinematic linear equation is FALSE?

During bungee jump (neglecting the air resistance), which of the following is FALSE?

• Distance / Displacement is NEGATIVE

• Velocity is NEGATIVE

• Acceleration / Gravitation is POSITIVE

Answer explanation

s = NEGATIVE (-ve) ;

v = NEGATIVE (-ve) ;

g = NEGATIVE (-ve)
