Question

Imagine you are lifting a toy car above your head and then holding it stationary above your head. While it is stationary what forces do you think act on the toy car?

A. applied and gravity

B. normal and applied

C. gravity and normal

D. tension and spring

Answer 1

The forces acting on a toy car held stationary above your head are the force of gravity pulling it downward and the applied force from your hand acting upward, which makes the answer 'A. applied and gravity'.

Step-by-step explanation:

While holding a toy car stationary above your head, two main forces act on the toy car: the force of gravity and the applied force of your hand. The force of gravity, or weight, pulls the toy car downward, while your applied force acts upward to counteract the toy car's weight. The correct answer to which forces act on the stationary toy car is A. applied and gravity. There is no normal force in this scenario as the car is not in contact with a horizontal surface, and neither tension nor spring forces are involved when holding the car stationary without any cord or spring attached to it.
