Consider the following situations:

A car is moving along a straight road at a constant speed.

A car is moving along a straight road while slowing down.

A car is moving along a straight road while speeding up.

A hockey puck slides along a smooth (i. e., frictionless) icy surface.

A hockey puck slides along a rough concrete surface.

A cockroach is speeding up from rest.

A rock is thrown horizontally; air resistance is negligible.

A rock is thrown horizontally; air resistance is substantial.

A rock is dropped vertically; air resistance is negligible.

Ahmed Lambert · Answer 1

Though no question is specified here but let analyzed experiences of each

Explanation:

1. Required a force to stop it (Law of inertial). Constant acceleration

2. will have reduced acceleration (deceleration)

3. Uniform acceleration may set in. it accelerate

4. maximized it speed since no friction affect it motion

5. accelerating. Vo=0 and V gradually increased

6. less or no friction opposes the motion

7. It experience reduce motion based on air friction

8. constant acceleration due to gravity

9. g can be a bit affected but still about equal
