What is the role of "conservation laws" in physics? 守恒定律在物理学中起什么作用?
What does it mean to say a quantity is "conserved"? 说一个量是‘守恒的’是什么意思?
If you fire a bullet horizontally and drop another simultaneously, which will hit the ground first? 如果你水平射击一颗子弹,同时释放另一颗子弹,哪颗会先落地?
What causes motion? 什么引起运动?
What is the difference between mass and weight? 质量与重量有什么区别?
Is an astronaut really weightless? 宇航员真的没有重量吗?
Describe the pairs of forces which illustrate Newton's third law when one block sits on top of another. 当一个块放在另一个块上时,描述体现牛顿第三定律的力对。
Describe static and kinetic friction and their applications. 描述静摩擦和动摩擦及其应用
Should you lock your wheels in a panic stop or back off the brake a bit to keep your wheels from locking? 如果你在紧急制动时恐慌地锁死车轮,还是稍微松开刹车以防止车轮锁死?
Do four-wheel drive vehicles stop quicker? 四驱车能更快停下来吗?
