If all of the forces acting on an object balance so that the net force is zero , thenA.the object must be at restB. the object’s speed will decreaseC. the object will follow a parbolic trajectoryD. the object’s direction of motion can change,but its speed cannot...
The force acting on an object is 20 N. If the acceleration of the object is 5 m/s², what is the mass of the object? A. 100 kg B. 4 kg C. 25 kg D. 15 kg 相关知识点: 试题来源: 解析 B。根据牛顿第二定律 F=ma,已知力 F 为 20N,加速度 a 为 5m/s²,可得质量 m=F/...
There are two forces acting on an object. One force has a magnitude of 39 N and is directed along the +x-axis. The other force has a magnitude of 25 N and is directed along the +y-axis. What is the direction of the acceleration of the object?
So, the normal force can act in any direction depending on the other forces acting. It always acts in a direction to keep the object at rest. Upvote • 0 Downvote Comments • 3 Mike D. Venkat is correct. I should have considered the general cases he states also. Rep...
