When displacement have the opposite derection what do you do to determine the magnitude?
Displacement is a vector quantity. Hence, while finding resultant vector we need to use vector algebra and the properties of vectors. If the 2 displacement vectore are in opposite directions,it means that the angle between them is 180degrees and hence we can directly subtract them.
Can distance be negative in physics?
No. Distance is never negative, and total distance travelled doesn't decrease during a trip. The distance from A to B is the same as the distance from B to A. Displacement, on the other hand, can be negative, and can decrease during a trip. The displacement from A to B is the same magnitude, but opposite sign, as the displacement from B to A. An example would be if you went from your home to a friend's house 1 mile to the east. After you reach your friend's house, you have travelled a distance of 1 mile and your displacement from your starting position is 1 mile. When you come back home from your friends house, you travel a distance of 1 more mile. Your total distance travelled is now 2 miles, but your displacement from your starting location is zero (because you are back where you started.) Distance does not have direction, and is always positive (or zero). Displacement has direction, and can be negative, positive, or zero.
Action-reaction forces are always the same but are in opposite?
Always the same magnitude but in opposite directions.
When two bodies interact the forces on the bodies are equal in magnitude and -------- in direction?
opposite
Can the resultant of two vectors be equal to zero?
Yes. A vector has magnitude and direction. If the vectors have equal magnitude and directly opposite directions their sum will be zero.
What is the difference between distance an displacement?
A distance is the length of the straight line path between 2 points. This is also known as a scalar value as it has a magnitude but no direction. A displacement is the distance and the direction between one point and another. This is also known as a vector as it has magnitude and direction as well. Note that the distance between two points, say, point A and point B is the same as the distance from point B to point A. It remains the same value regardless of the direction of travel. On the other hand, if a displacement between point A and point B was 1 mile North, it cannot be reversed. The displacement between point B and point A is 1 mile South - the same distance but an opposite direction.

When do two vectors cancel each other?
When they have the same magnitude, but opposite directions.When they have the same magnitude, but opposite directions.When they have the same magnitude, but opposite directions.When they have the same magnitude, but opposite directions.
Why the ratio of displacement to distance is never greater than 1?
The technical answer is that displacement is the vector sum of the distances. An example to illustrate the difference in less technical terms, distance travelled in one direction added to the same distance in the opposite direction will result in the total distance being twice the distance of each leg but the total displacement is 0.
What is the result of two displacment vectors having opposite directions?
It is a displacement equal in magnitude to the difference between the two vectors, and in the direction of the larger vector.
What is the magnitude of the displacement of a car that travels half a lap along a circle that has a radius of 175 m?
Displacement is the straight line distance between two points. If the two points are a half a lap apart on a circular path then the straight line distance is the diameter of the circle; 350 m. What that means is that displacement describes only the relationship between end position and starting position, so the car stops at a point on the opposite side of the circle, 350m from the start. Displacement is not necessarily distance traveled. If the car had gone completely around the circle and stopped where it started, the displacement would be zero, even though it has traveled nearly 1100 m.
The application of a force through a distance?
Work = Force * displacement if the displacement and the force are parallel - work is positive if force and displacement are in the same direction, negative if they have opposite direction. At an angle Work = Force * displacement * cos(θ) where θ is the angle between the force and displacement vectors.
Explain what is the negative sign in hook's law mean?
It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.It means that the force is in a direction opposite to the displacement of the spring.
What is the opposite side of a rectangular?
Non-rectangular.
What is a couple according to physics?
A couple is two forces equal and opposite to each other and separated by a distance. The magnitude of the force times the distance is called a moment
