Question

What are the forces acting on the shopping cart when a woman pushes it?

Answer 1

Answer:

1. frictional force, static force, pressure, etc.

Answer 2

Air resistance, friction , gravity and force exerted by woman.

Explanation:

• Air resistance, friction, and gravity are all outside forces working on the cart, causing it to lose speed if there's no continuous propulsion.

• Newton's Second law states that the more force applied on an object, the more acceleration it'll have.

• If a woman gently pushes the handcart along, it'll go slowly and stop quickly. However, if more force is applied, the cart will go much faster, and take longer to stop.

• Air resistance and friction are forces opposing the motion of cart.
• Force exerted by woman is acting in direction of motion of cart.  
• Gravity is in downward direction binding the objects to the ground.
