If mass is added to a battery-powered toy car. why its speed will decrease?

This is because the work done in order to move the toy car is smaller than that of the car with the added mass, and so the battery will have to work harder to move the toy car with the mass added

Does speed decrease with increasing mass?
yes as long as your muscle mass does not change.
What happens when the mass of either the balls is increased in simulation?
the balls decrease in speed
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
As the mass of an object moving at a given speed decreases its kinetic energy does what?
Decrease, if its velocity is held constant. Because p = mv, a smaller m results in a smaller p if v is the same. decrease
What is the effect of mass on torque Wind turbine blades are lengthy to increase torque and to decrease speed. How can i decrease speed using mass Or can I increase torque by increasing MASS?
Mass has no effect on torque. Torque is the product of distance (from the axis), force, and an angular function. Mass can, however, make the turbine more stable - it will take longer to react to variations in wind. More mass will increase the MOMENT OF INERTIA (rotational inertia).
When mass is added to a moving cart what happens to its acceleration?
The cart's acceleration will decrease as its mass increases. This is why you must exert progressively more force on a shopping cart to move it along as items are added to it. If you were to continue to add items to the cart but not change how hard you push it, the cart would eventually become "impossible" to push.
Does the effect of gravity decrease your speed?
If you're moving toward a relatively large mass ... large enough so thatgravitational forces between you and any other mass are insignificant bycomparison ... then the forces of gravity increase your speed toward it.If you're moving away from a relatively large mass ... large enough so thatgravitational forces between you and any other mass are insignificant bycomparison ... then the forces of gravity decrease your speed away from it.
What happens to the kinetic energy of a snowball as a rolls across the lawn and gains mass?
That depends on what happens to its speed. The formula for kinetic energy is:KE = m(v)^2, in which m is mass in kg and vis speed in m/s.If either the mass or the speed increases, the kinetic energy will increase. So if the mass of the rolling snowball increases, but the speed remains constant, its kinetic energy will increase.However, in reality, due to friction between the snowball and the ground, the speed will decrease until the snowball stops. So the kinetic energy under natural conditions would decrease, even though the mass increases.

What decreases the centripetal force?
If a body of mass m is in uniform circular motion with speed v and radius r, then the force acting on it has magnitude F = mv2 / r and is directed towards the centre of the circle. This is termed a "centripetal" (meaning "centre-seeking") force. To decrease the magnitude of the centripetal force, you must therefore either decrease the mass of the body, decrease the orbital speed, or increase the radius of the orbit.
