Newton's Laws

Which of Newton's Three Laws does the following statement satisfy? The relationship between an object's mass (m), its acceleration (a), and the applied force F is F=ma. Acceleration and force are vectors. This law requires that the direction of the acceleration vector is in the same direction as the force vector.

Which of Newton's Laws does this situation represent? Imagine a ball moving in a straight line directly toward when another ball collides with it. The moving ball exerts a force on the ball at rest. This causes the ball at rest to accelerate. However, the ball at rest also exerts the same magnitude of force (in the opposite direction) of the moving ball. This will cause the moving ball to decelerate or even move in another direction.

In the following example, what are the forces that are acting on the ball? Check all that apply. If a ball is thrown in the air, it will keep going the same velocity unless a force changes the velocity (speed and direction).
