An object is lanuched at angle of 45 degrees. If I only have mass and distance travled given, how can I find the velocity of the object?
Velocity is a measure of how fast an object is moving in a specific direction. It is a vector quantity, which means it has both magnitude (speed) and direction.
Velocity is calculated by dividing the change in an object's position by the time it took for that change to occur. In other words, it is the displacement divided by the time. The standard unit for velocity is meters per second (m/s).
According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Therefore, a larger mass will result in a smaller velocity for the same amount of force applied.
The distance an object travels has no effect on its velocity. Velocity only depends on the displacement and time taken to travel that distance. However, the average velocity can be affected by changes in distance, as it is calculated by dividing the total displacement by the total time taken.
Yes, velocity can be negative. This indicates that the object is moving in the opposite direction of the chosen reference frame. For example, if the reference frame is moving to the right, an object moving to the left would have a negative velocity.
