Describe four examples of acceleration you see during your day. Choose an object that is slowing down, one that is speeding up, one that is moving at a constant speed but changing direction, and one that is moving at a constant velocity with zero

Two physics books, A and B, are placed on top of each other on a table. Book A's mass is 2 kg and book B's mass is 1 kg. Book A is placed on book B. What is the reaction book B exerts onto book A?

Which of the following parts of John Dalton's atomic theory, if correct, would have made it impossible for Marie Curie's discovery that new elements can be produced when elements are bombarded with neutrons? All matter is made of atoms.

A friend tosses a baseball out of his second floor window with initial velocity of 4.3m/s (42degrees below the horizontal). The ball starts from a height of 3.9m and you catch the ball 1.4m above the ground.
