Question 2
When the problem states that a cart is moving along a road at a constant velocity. What does this mean about the forces acting on the cart?(1 point)
Responses

Constant velocity and force have no relationship.
Constant velocity and force have no relationship.

There are no forces acting on the cart.

Constant velocity increases net force.
Constant velocity increases net force.

All the forces acting on the cart equal zero net force.

Answer 1

Let's address each question:

Question 1: Which choice would increase the net force on the cart?

• Applying a braking force by dragging your foot.

This choice would increase the net force on the cart because applying a braking force is an external force that affects its current state of motion. The other options either reduce friction or reduce mass but do not inherently increase the net force acting on the cart.

Question 2: When the problem states that a cart is moving along a road at a constant velocity, what does this mean about the forces acting on the cart?

• All the forces acting on the cart equal zero net force.

When an object moves at a constant velocity, it implies that the forces acting on it are balanced, resulting in a net force of zero. In other words, the forces acting on the cart are equal in magnitude but opposite in direction, resulting in no change in speed or direction of motion.
