The velocity of an object moving in a 2D plane can be calculated by dividing the displacement in the x and y directions by the time taken. This can be represented by the equation v = d/t, where v is the velocity, d is the displacement, and t is the time.
Speed refers to how fast an object is moving, while velocity refers to how fast an object is moving in a specific direction. For example, a car can have a speed of 60 km/h, but if it is moving north at that speed, its velocity would be 60 km/h north.
Acceleration is the rate of change of an object's velocity. In a 2D plane, acceleration can cause an object to change its speed, direction, or both. For example, if a car is accelerating while turning, its velocity vector will change in both speed and direction.
The net force acting on an object moving in a 2D plane can be calculated by adding all the individual forces acting on the object. This can be represented by the equation Fnet = ∑F, where Fnet is the net force and F is the individual force.
Vectors are used to represent the magnitude and direction of an object's motion in a 2D plane. The displacement, velocity, and acceleration of an object are all vector quantities and can be represented by arrows with direction and magnitude. This allows for a more accurate and comprehensive description of an object's motion in a 2D plane.
