Description
"Synthesis of Two Forces on the Same Straight Line" Motion and Force PPT Courseware
Pre-study tips
1. If the effect produced by a force is the same as the effect produced by two forces acting together, the force is called the _________ of those two forces.
2. The resultant force of two forces with the same direction on the same straight line is equal to the ________ of the two component forces, and the direction is the same as _________.
3. The resultant force of two forces in opposite directions on the same straight line is equal to the magnitude of the two component forces, and the direction is the same as the direction of _________.
4. Is the resultant force always greater than the component forces?
Research conclusion:
Two forces in the same direction acting along the same straight line, the direction of the resultant force is ________, and the magnitude is equal to the magnitude of the two forces______;
Two forces acting in opposite directions along the same straight line have the same direction of the resultant force_____________ and their magnitude is equal to the magnitude of the two forces____.
In conclusion:
same direction
Size: F combined=F1+F2
Direction: Same as the direction of both forces
opposite direction
Size: F together = F large - F small
Direction: Same as the direction of greater force
1. As shown in the figure, the cube metal block weighs 20 N, and F is always 5 N. The pressures on the supporting surface are:
Fc =G-F= 20N-5 N = 15N
Fd=G+F= 20N+5 N = 25N
2. Regarding the combination of two forces on the same straight line, which of the following statements is correct ( )
A. The resultant force of two non-zero forces must not be zero.
B. The resultant force of two forces must be greater than any one of them.
C. To find the resultant of two forces is to add the magnitude of the two forces.
D. Regardless of the directions of the two forces, the direction of the resultant force is always consistent with the direction of the larger force.
