yes. this is the baseline understanding for rotational motion. Think of driving a car, if you turn the wheel of the car then you are directing the frictional force near perpendicular to your velocity and thus "turn" the car.
More precisely, the car's acceleration is radial while its velocity is tangential and thus the car is following a rotational path, during the turning phase of travel.
a vector quantity has both direction (sign) and magnitude like displacement towards right or left (direction) and has a certain value (magnitude)
polarized light
If the equal and opposite forces are separated by a certain distance they are called as couple. If the equal and opposite forces are not seperated by a certain distance their resultant is zero as per Parallelogram Law of Vector Addition.
A change in position in a certain amount of time is called motion.
An antonym (opposite) for certain is maybe not certain
no
Yes, the object will move in a curved path due to the combined effect of the velocity in one direction and acceleration in the perpendicular direction. This is known as projectile motion. The acceleration perpendicular to the initial velocity will change the direction of motion but not the speed.
foliation
It could be, but without the diagram it is not possible to be certain.
The rock exhibits foliation when certain minerals recrystallize with a preferred orientation perpendicular to the compressional force. Foliation creates a layered structure in the rock, giving it a banded appearance and indicating the direction of the applied stress during metamorphism.
The Poisson's Ratio for carbon graphite is typically around 0.15 to 0.3, indicating that when a material is stretched in one direction, it tends to contract in the perpendicular direction by a certain extent.
no because it is what it is today and tomorrow and always sorry
just see if its a right angle
The rock is said to exhibit foliation. Foliation is a type of deformation that occurs in rocks under intense pressure, causing individual minerals to align in a preferred orientation parallel to the direction of compressional forces.
Velocity is the measure of speed in a certain direction. It is a vector quantity that includes both the speed of an object and the direction in which it is moving.
wind.
It is a plane perpendicular to the lens at the focal distance from the lens. All parallel light entering the lens from a certain direction falls on a single point somewhere on this plane. Where the point of light falls depends on what angle the "wall" of light enters the lens.
