they have both direction and magnitude. They can go in one direction and thus have a magnitude in that direction... uh yeah
Less surface area contacting the ground reduces friction. Wheels are useful for moving heavy objects so you don't hurt your back.
all of the above
The three types of vectors are position vectors, displacement vectors, and force vectors. Position vectors represent the position of a point in space relative to a reference point, displacement vectors represent the change in position of an object, and force vectors represent the interaction between objects that can cause acceleration.
yes moving objects have impulse
All moving objects have Momentum.
keep distance with moving objects.
Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.
Force vectors are quantities that have both magnitude and direction, representing the push or pull on an object. They affect the motion of objects by changing their speed, direction, or both. Forces can cause objects to accelerate, decelerate, change direction, or remain at rest.
Special relativity is always applicable, but only really useful when you are considering objects moving close to the speed of light. General relativity should be used when objects are very heavy or dense.
Velocity addition is used when dealing with two objects moving at different velocities relative to each other. It helps calculate the combined velocity of the objects when seen from a different reference frame.
Vectors are commonly used in various practical applications and real-life scenarios, such as navigation, engineering, physics, and computer graphics. In navigation, vectors are used to represent the direction and magnitude of movement, helping in determining the position of objects or vehicles. In engineering, vectors are employed in structural analysis to calculate forces and moments acting on structures. In physics, vectors are used to describe quantities like velocity, acceleration, and force, aiding in the understanding of motion and interactions between objects. In computer graphics, vectors are utilized to represent shapes, positions, and movements of objects in a virtual environment, enabling the creation of realistic visual effects and animations.
