The unit of rate of change is whatever it is that is changing, divided by time units. For example, if you measure rate of change of dollars in your bank account, you would have something like dollars / month; for acceleration, the unit commonly used is (meters / second) / second, etc.
1 km per second is defined as equal to 1000 meters per second. Therefore, a speed of 15 meters per second is 15/1000 km per second or 0.015 km per second.
767miles/hour = 767 x 1609.344 meters/hour = 767 x 1609.344 meters / 3600 seconds = 343 meters per second (approx)
5 metres per second squared

No, that's not correct.The acceleration of gravity means that for each second that passes, falling objects fallat a speed that's 9.8 meters per second fasterthan it was one second earlier.
2.
The pull of gravity on any given object is of course the objects weight. The acceleration an object undergoes while falling due to gravity's pull is approximately 9.8 m/s/s. (meters per second per second)
The traditional acceleration due to gravity is 9.8 meters per second per second
The acceleration depends on the force of gravity. Near Earth's surface, this acceleration is approximately 9.8 meters per second square.
An object affected by the gravity of the Earth is falling at 9.8 meters per second per second, also written as 9.8 m/s^2.
Objects in a vacuum will NOT fall at a constant rate; they will fall faster and faster. In other words, they will continuously accelerate. The acceleration near the surface of the Earth is about 9.8 meters per square second. This is not a speed - it means that every second, the speed of the object increases by 9.8 meters per second.
By Newton's Second Law: force = mass x acceleration, or acceleration = force / mass. Since there is a force, there should be an acceleration - a change of velocity.
Acceleration is not measured in meters/second. Meters/second is a unit of speed. Since acceleration is defined as change of speed divided by time, the units are meters/second/second, usually written as meters/second2.
Assuming (1) the object starts from rest, (2) air resistance is insignificant, the object speeds up by about 9.8 meters/second every second. That's the strength of the gravitational field. Just multiply this acceleration (9.8 meters/second2) by the time.
All objects fall to the center of the earth a 9.8 ms per second. so they will gain acceleration until the reach the approximate rate of 9.8 meters per second.
The pull of gravity on any given object is of course the objects weight. The acceleration an object undergoes while falling due to gravity's pull is approximately 9.8 m/s/s. (meters per second per second)
