a. the object is turning
b. the object is not moving
c. the object is speeding up
d. the object is slowing down
e. this situation would not be physically possible
acceleration is the rate of change of velocity with respect to time.
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
In that case, the direction will change.
If that happens, the body's speed will decrease.
The velocity stays the same, it is constant
acceleration is the rate of change of velocity with respect to time.
Its velocity decreases because gravity is pulling on it as it goes up. Its acceleration increases.
It is the velocity that increases.
The velocity increases at a constant rate.
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
"Acceleration" implies that the velocity changes.
The velocity changes. called acceleration.
In that case, the direction will change.
a = F/m, where a is acceleration, F is net force, and m is mass in kilograms.
If that happens, the body's speed will decrease.
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
