Motion of object in 2 dimensions

In summary, displacement is the shortest distance between two points in an object's motion, while distance is the total length traveled. Velocity includes direction while speed does not, and acceleration is the change in velocity over time. Projectile motion is the path of an object under the influence of gravity. Air resistance is a force that can slow down and change the trajectory of an object, with larger surface areas experiencing more resistance.

A ball is kicked from 12 m high traveling horizontally at 1.3 m/s.


How would the horizontal motion affect the vertical motion and why?

Related to Motion of object in 2 dimensions

What is the difference between displacement and distance?

Displacement is the shortest distance between the starting and ending point of an object’s motion in a specific direction, while distance is the total length of the path traveled by an object. In other words, displacement is a vector quantity that includes both magnitude and direction, while distance is a scalar quantity that only includes magnitude.

How is velocity different from speed?

Velocity and speed are both measurements of an object’s motion, but they differ in that velocity includes direction and speed does not. Velocity is a vector quantity, while speed is a scalar quantity. For example, a car traveling at 50 miles per hour due east has a velocity of 50 mph, while a car traveling at 50 miles per hour in any direction has a speed of 50 mph.

What is acceleration and how is it calculated?

Acceleration is the rate at which an object’s velocity changes. It is calculated by dividing the change in velocity by the change in time. The unit for acceleration is meters per second squared (m/s²). If an object’s velocity increases by 10 m/s over a time of 5 seconds, the acceleration would be 2 m/s².

What is projectile motion?

Projectile motion is the motion of an object that is launched into the air and then moves under the influence of gravity alone. Examples of projectile motion include a basketball being thrown into the air, or a rocket being launched into space.

How does air resistance affect the motion of an object?

Air resistance is a force that acts in the opposite direction of an object’s motion through the air. It can slow down the speed of an object and change its trajectory. The larger the surface area of an object, the greater the air resistance it experiences. For example, a feather will experience more air resistance than a bullet due to its larger surface area.
