It is because g oppose acceleration meaning that it becoms negative acceleration

**physics**

Current velocity = (time)*(acceleration) + initial velocity 12 = (0.96)*acceleration + 0 acceleration = 12.5 m/s2

examples of: 1) acceleration against the direction of motion 2) acceleration in direction of motion 3)acceleration is uniform 4)acceleration is non-uniform

**Physics**

1) would dropping an object higher than it's usual point change it's acceleration? 2) would throwing an object upward change it's acceleration? 3)does the mass of an object affect it's acceleration? 4) how does altitude affect the value of g? what other factors cause this ...

What is a tire's angular acceleration if the tangential acceleration at a radius of 0.15 m is 9.4 x 10-2 m/s2?

**physics**

acceleration is 9.8 m/s^2 (!), Acceleration shows how the speed changed during the 1 second of accelerated motion

**physics**

(1) The resultant force is the mass times the acceleration. (2) The acceleration is zero. Therefore: __________________
