Yes (less than 90 degrees, acceleration vector would have a component in the direction of the velocity vector while speed is increasing).hannahtuell said:Is the angle between the acceleration vector and the velocity vector of an this object when it is speeding up greater or less than 90 degrees?
Acceleration is the rate at which an object's velocity changes over time, while velocity is the speed and direction of an object's motion.
Acceleration and velocity are related in that acceleration is the derivative of velocity with respect to time. This means that acceleration is the change in velocity over time.
Acceleration can be calculated by dividing the change in velocity by the change in time, while velocity can be calculated by dividing the displacement by the change in time.
The units for acceleration are typically meters per second squared (m/s^2), while the units for velocity are meters per second (m/s).
Acceleration can be observed when a car speeds up or slows down, while velocity can be observed when a plane takes off or a person runs at a constant speed.
