3 m/s
To find the average speed between time=0 and time=2, divide the distance traveled by the time (in this case 2 seconds).
Yes, velocity can be 0 while speed is not 0. Velocity is a vector quantity that includes both speed and direction, so if an object is moving in a straight line and comes to a stop, its velocity is 0 but its speed is not 0. Speed, on the other hand, is a scalar quantity that only considers the magnitude of the motion, regardless of direction.
0
0
0 divided by 5 equals 0. 5 divided by 0 equals undefined, not 0.Any number divided by 0 is undefined.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
An object at a constant speed has no net force acting on it because the forces are balanced. When there is no net force, the object will continue to move at a constant speed due to inertia, which is the tendency of an object to maintain its state of motion.
0 m/s
haha 0
That depends upon what the object has done for the 20 seconds since t = 0 seconds.
The speed of an object at rest is 0 m/s. When an object is not moving, its speed is considered to be zero.
Yes, an object can have a speed of 0 while still having a non-zero acceleration. This can happen when the object is changing direction but not speed, such as in circular motion or in the case of an object at rest on an incline under the influence of gravity.
0 m/s
An object moving at a constant speed in a straight line has an acceleration of 0. An object at rest also has an acceleration of 0. So, the two things I see in common are their accelerations, which are both 0.
The speed of a stationary object is 0 m/s, as it is not moving.
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
We can only tell average speed from those two pieces of information. 3,000 miles in 5 hours equals an average speed of 600 mph.
