... 7. When a junked car is crushed into a compact cube, does its mass change? Its volume? Its weight? 8. If an elephant were chasing you, its enormous mass would be very threatening. But if you zigzagged, the elephant’s mass would be to your advantage. Why? 9. When you compress a sponge, which quantity ...

Newton`s Second Law of Motion
... As stated, Newton’s first law of motion governs the properties of inertia that an object at rest stays at rest and an object in motion remain in motion in the absence of an external force. However, it is observed that an object that tends to move comes to rest at a certain point as well as objects t ...

... • Every object continues in a state of rest, or in a state of motion in a straight line at constant speed, unless it is compelled to change that state by forces exerted upon it • In other words: With no force exerted on it, an object in motion remains in motion in a straight line, an object at rest ...
