Does our speed/velocity on earth change if one reference point is the earth's surface and the other is Pluto?

How do Speed and Acceleration relate?

people who can jumped 2sec in the air, how long will he stay if he jumped from top to ground, the height is 5m

a man jumped 2sec vertical, how long can he hang on if he jumped to front

if the force is 6n, the mass is 6kg, what is the acceleration

Does displacement depend on direction?

How are speed and velocity different in their natures?

A steel beam of uniform cross section weighs 2.5 X 105 Newton's. If it is 5 meters long, what force is needed to lift one end of it?

If you go to school and go back home at the same position where you start, what is your displacement?

What is the relationship between acceleration and velocity?

What different between distance and displacement?

The average speed is the average speed of an object in a variable speed motion (T or F)

How are speed and velocity different?

why the average velocity is different with velocity

Can You calculate speed if the reference point is a moving car?

What is the difference between average velocity and instantaneous velocity?

h throw a ball vertical, it use 7sec to touched the ground, how high have the ball been

if a car drive 5m per sec, the car weight is 700kg, what is the force on the car

how do we calculate the acceleration if we know the force and the mass

What equation would I use for hang time problems and why?

If a car is slowing down in its acceleration, does its velocity act against the acceleration force or with it?

A painter weighing 875 Newton's stands on a plank 3 meters long, which is supported at each end by a stepladder. The plank weighs 223 Newton's. If the painter stands 1 meter from one end of the plank, what force does each end of the ladder exert?

A car is travelling from A to B at 10 m/s. On the half way the car changes its speed from 10 m/s into 15 m/s. The total distance between A and B is 1200 m. What is the average speed of the car?

If you throw a ball from the ground to reach the highest point, is the velocity positive or negative?

Is speed always positive?

When you answer a question someone posted, give the paragraph and page number from the text or post the website where you found your information. ANSWERS WILL NOT COUNT UNLESS YOU CAN PROVE IT IS CORRECT!

（T or F) The direction of instantaneous velocity is always constant motion, it must be uniform and linear motion

what’s the connection between velocity and motion

what is the realtionship between velocity and acceleration
