unknownplaya said:Hello. I have a question on this problem.
What are two quantities of an object launched parallel to the ground which are equal to zero?
I think one of the two is vertical velocity, but I'm not sure.
please help me with this problem. Thank you.
Motion in a plane refers to the movement of an object in two dimensions, typically on a flat surface such as a table or a coordinate plane. It involves both horizontal and vertical motion, and can be described using vectors.
Vectors are mathematical quantities that have both magnitude (size) and direction. In the context of motion in a plane, they are used to represent the displacement and velocity of an object.
Displacement is calculated by finding the difference between an object's initial and final position, while velocity is calculated by dividing the displacement by the time interval over which it occurred. Both of these quantities can be represented using vectors.
Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that takes into account both the speed and direction of an object's motion. This means that two objects can have the same speed but different velocities if they are moving in different directions.
Motion in a plane is closely related to other concepts in physics such as forces, acceleration, and Newton's laws of motion. It also forms the basis for more complex motions, such as projectile motion and circular motion, which are important in fields such as mechanics and astrophysics.
