1.)Why is slowing down acceleration? 2.)what are 3 ways something can accelerate?
3.)if a person is walking at a constant velocity of 3 m/a, are they accelerating?
4.)A car is speeding up after being at a stop light, is this an example of speed, velocity, or acceleration ?

Please hurry

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart

In a heat engine if 1000 j of heat enters the system and the piston does 500j of work, what is the final internal energy of the system if the inital energy was 2000 j1.write the equation2.list out your known variables 3. plug the numbers into the equations4.solve 5.write your solution statement that includes initial energy and final energy added.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
