Use round wheels to roll the load, lighten the weight by removing attached or contained objects, or place a smoother surface betwen the object and the floor.
Water or other fluids can be used to decrease the resistance, but only if they remain between the object and the floor.

What is the difference between drag and friction?
Drag is a force that resists an object's motion through a fluid (such as air or water), while friction is the force that resists an object's motion when in contact with a surface. Drag occurs in fluids, while friction occurs between solid surfaces.
As a moving object's velocity decreases its momentum decreases?
False. The momentum of an object is the product of its mass and velocity, so if the velocity decreases while the mass remains constant, the momentum of the object will decrease.
What are Two ways you can decrease the density of an object?
You can decrease the density of an object by increasing its volume while keeping the mass constant, or by decreasing its mass while keeping the volume constant.
What forces act apon objects in motion?
The main forces that act on objects in motion are gravitational force, frictional force, and air resistance. Gravitational force pulls objects towards the center of the Earth, while frictional force resists the motion of objects against surfaces, and air resistance opposes the motion of objects moving through the air.
On a distance time graph how can you tell which object is moving?
You can tell which object is moving by looking at the slope of the graph. A steeper slope indicates a faster-moving object, while a flatter slope indicates a slower-moving object. Additionally, a positive slope indicates forward motion, while a negative slope indicates backward motion.

Does the distance from the sun increase or decrease while moving away from the equator?
Increase

Rate of change of velocity of a moving object?
The rate of change of velocity of a moving object is known as acceleration. Acceleration can be calculated by dividing the change in velocity by the time taken for the change to occur. Positive acceleration represents an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity.
What directions Do the forces of air resistance and weight act on a falling object?
The weight of a falling object acts downwards, while air resistance acts in the opposite direction of the object's motion. Weight is the force of gravity pulling the object toward the ground, while air resistance is the frictional force that opposes the object's motion through the air.
How are velocity and acceleration different?
Velocity is the rate of change of position of an object with respect to time, while acceleration is the rate of change of velocity of an object with respect to time. Velocity describes how fast an object is moving and in which direction, while acceleration describes how quickly the velocity of an object is changing, either in speed or direction.
What is the difference between collided into and collided with?
"Collided into" implies one object moving and striking another object. "Collided with" suggests both objects moving and coming into contact with each other.
Why do some objects move so fast and some move so slow?
The speed at which objects move depends on various factors such as the forces acting upon them, their mass, and the environment they are in. Objects can move fast due to forces like gravity or propulsion, while others may move slowly due to factors like friction or resistance. Ultimately, an object's speed is determined by the balance of these different influences.
Do objects have inertia only when they are moving?
No, objects have inertia even when they are not moving. Inertia is the tendency of an object to resist changes in its velocity, whether it is at rest or in motion.
