## How do you find speed with only distance?

Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours.

## Which measurements are necessary for determining both the speed and velocity of a moving object?

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second .

## What is the measurement for velocity?

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).

## How do you calculate velocity from time and distance?

Provided an object traveled 500 meters in 3 minutes , to calculate the average velocity you should take the following steps:

- Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
- Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .

## Is it possible for an object’s speed to decrease while its acceleration increases?

Is it possible for an object’s velocity to increase while its acceleration decreases? No, this is impossible because of the way in which acceleration is defined. No, because if acceleration is decreasing the object will be slowing down. No, because velocity and acceleration must always be in the same direction.

## What happens to acceleration if mass is constant and force increases?

Now explain what it means to say, “Acceleration is inversely proportional to mass.” It means that if force is constant, as mass is increased, acceleration decreases. resistance to changes in motion (also known as INERTIA.)
