1.动量公式是什么,它是矢量吗?
动量:p=mv {p:动量(kg/s),m:质量(kg),v:速度(m/s),方向与速度方向相同} ,是矢量.
Momentum:p = mv (p:momentum (kg / s),m:mass (kg),v:velocity (m / s),direction and speed in the same direction) is a vector.
2.简述牛顿第三定律.
牛顿第三定律:两个物体间的作用力和反作用力总是大小相等,方向相反,并且作用在同一直线上 .F1=-F2
①力的作用是相互的.同时出现,同时消失.
②相互作用力一定是相同性质的力
③作用力和反作用力作用在两个物体上,产生的作用不能相互抵消.
④作用力也可以叫做反作用力,只是选择的参照物不同
⑤作用力和反作用力因为作用点不在同一个物体上,所以不能求合力
Newton's Third Law:the force between two objects and reaction are always equal and opposite,and the role of a straight line.F1 =- F2
① force's role is mutual.Also appear at the same time disappear.
② interaction force must be of the same nature
③ reaction force and the role of the two objects,the resulting effect can not cancel each other out.
④ called the reaction force can only choose different reference
⑤ force and reaction force acting point is not the same as an object,it can not seek together
3 如果一个箱子向右侧滑动,求摩擦力的方向?

Left
4 陈述一下质量和重量的一点区别
1.定义不同.质量是物体惯性的量度,它是任何物体都固有的一种属性.重量则反映了物体所受重力的大小,它是受地球的吸引而引起的.
2.质量是标量.重量是矢量.
1.Different definition.Quality is the measure of inertia an object,any object which is an inherent property of all.Suffered weight reflects the gravity of the size of the object,it is attracted by the Earth caused.
2.Quality is the scalar.Weight vector.

1 动量的公式是什么?它是一个矢量么?
Answer: The formula of momentum is: p=mv
where p is the momentum, m is the mass and v is the velocity.
It is definitely a vector because the velocity v is a vector with direction.
2 简述牛顿第三定律.
[就是作用力和反作用力]
Answer: The Newton's Third Law is: For every action, there is an equal and opposite reaction. This law states that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
3 如果一个盒子向右滑行,那么作用在盒上的摩擦力的方向是什么?
Answer: The direction of the force of friction on the box is to the left.
4 说出质量和重量的一个不同点。
Answer: Mass is a measure of how much matter an object has. Weight is a measure of how strongly gravity pulls on that matter.
If someone travels to the moon his weight would change because the pull of gravity is weaker there than on Earth but, his mass would stay the same because he are still made up of the same amount of matter.

3.如果一个盒子向右滑动,作用在盒子上的摩擦力向哪个方向?
答:向左Direction left
4.解释说明质量和重量的不同点(差别).
答:物体含有物质的多少叫质量.质量不随物体形状、状态、空间位置的改变而改变,是物质的基本属性.重量是物体在引力作用下受力大小的亮度,它会随着产生引力的物体的变化而变化.Objects contain substances called quality. How much does not object shape, with the quality, the space is changed, basic attribute of material. The weight is under gravity force objects in the size of the brightness, it will produce gravitational objects with the changes.
