Topic explanation

Standard explanation

Acceleration is a=dv/dt=d^2s/dt^2 and does not by itself tell the direction of motion.

Key points

• Acceleration as rate of velocity
• rule
• worked example
• Acceleration as rate of velocity: Acceleration is a=dv/dt=d^2s/dt^2 and does not by itself tell the direction of motion.
• CONCEPT AND RULE: Acceleration is a=dv/dt=d^2s/dt^2 and does not by itself tell the direction of motion.
• METHOD: For acceleration as rate of velocity, identify the given information and required result. Select the
• Acceleration is a=dv/dt=d^2s/dt^2 and does not by itself tell the direction of motion.
• Worked pattern: For s=t³, v=3t² and a=6t.
