Test your knowledge
• What is meant by inertia?• What does Newton’s first law of motion tell you
about the difference between motion in a straight line and motion along a curve
• How does mass differ from weight?• If your mass is 70 kg on earth what is it on the
moon?• If you weight 110 pounds on the earth do you
weight 110 pounds on the moon?• What is surface gravity measure?• What is the escape velocity?• A cinder block can be weightless in space. Would
you want to kick it with your bare foot? Even if it is weightless, does it have mass?
• Does g (the acceleration of gravity) depend on the altitude above sea level?
• Explain how a large planet could have a surface gravity smaller than a smaller planet.
