An empty wagon rolls easy but a loaded wagon is more difficult to roll Using your knowledge of friction force and weight explain why this is so?

Force = mass x acceleration
Assuming we want the same acceleration such as 0 to 60 mph in 10 seconds.
The loaded wagon has more mass. Hence, it requires more force to move it.

When the wagon is loaded, it increases the weight acting on the wheels, which results in an increase in friction between the wheels and the surface. This increased friction force makes it more difficult for the loaded wagon to roll compared to the empty wagon. Additionally, the weight of the load creates a downward force that presses the wheels against the ground, increasing the friction force further.

Difference between friction batons and spring loaded batons?
Friction batons require manual extension by pulling them out, while spring-loaded batons use a spring mechanism for automatic extension with the push of a button. Friction batons are more prone to user error and may require more force to extend, while spring-loaded batons offer quicker deployment and can be easier to handle in high-pressure situations.
What is a loaded caliper versus an unloaded caliper?
A loaded caliper is one in which the brake pads are in contact with the rotor, creating friction for braking. An unloaded caliper is when the brake pads are not in contact with the rotor, allowing the wheel to spin freely without any braking force applied.
What will happen to the velocity of the car as sand is loaded onto it?
The velocity of the car will decrease as sand is loaded onto it due to the increase in mass. This increase in mass requires more force to accelerate the car to maintain the same velocity. Additionally, the added weight may affect the car's ability to overcome friction and air resistance, further reducing its velocity.
How does the buoyant force on a boat change if the boat is loaded?
The heavier the boat is loaded, the deeper in the water the boat will float.
Is a pram balanced or unbalanced?
A pram is typically balanced when empty or when evenly loaded with weight. However, it can become unbalanced if the weight distribution is not even, causing it to tip over or become difficult to maneuver. It's important to distribute weight evenly to maintain balance.

Why does loaded truck start more slowly than an empty truck?
becoz loaded truck has got more weight than the empty truck.....so becoz of which loaded truck has got more friction in tyres compared to empty truck...this may the reason why loaded truck starts slow than the empty truck
Explain how the induction motor gets loaded when the DC generator is loaded?
when the dc generator is loaded current will be drawn from it, therefore a back emf Will be generated, which opposes the motion of a generator, and hence, that opposition loads the three phase generator
Why is it more difficult to stop a fully loaded truck than a unloaded one?
because it is affected by gravity
How donuts harmful for health?
Here we go: * Loaded with sugar. * Can you say loaded with trans fats or damaged fats due to deep frying? * Just white-devoid-of-nutrition-&-fiber flour. Do we really have to explain more?

What determines if a rifle is fully loaded if the bullet is not chambered in the breech or rear of the barrel and if the bolt is open could this rifle fully loaded or not fully loaded?
What you are describing could be a rifle that is not loaded, partially loaded or fully loaded, but, does not have a round chambered.
What kind of knobs do you put on interior double doors if you want each to be able to be opened?
Fake knobs: The way I've seen interior double doors installed is with a spring-loaded ball on the top of each door and a striker plate with a dimple that receives the spring loaded ball installed into the frame - it's difficult to explain. If you imagine a regular passage set installed on the top of each door, it's like that, except instead of a wedge shaped bolt to hold the door in place, a spring loaded ball is used so that the door can be closed and opened without turning a knob. Then fake (non turning) knobs are installed at standard height.
