Question | Answer |
---|---|
21- What is inertia? | The tendency of an object to remain in its current state, (in motion or at rest) |
21 - What is Newton's first law of motion? | An object at rest tends to stay at rest, and an object in motion tends to stay in motion until acted upon by an outside force. |
22 - What is the equation that expresses Newton's second law of motion? | Force = mass x acceleration (F=m x a) |
22 - What is another name for the second law of motion? | The law of acceleration |
22 - If the same force is applied to 2 objects with different masses, what will be the effect on their accelerations? | The object with the smaller mass will accelerate faster than the object with the greater mass. |
22 - If you wish to increase the acceleration of an object, how must the force change? | It must increase. |
