A cart is rolling down a special ramp where there is no friction at all What will happen if the amount of mass on the cart is increased?
The cart will move at a constant velocity.
Does the speed of a ball rolling down a ramp change with the kind of surfacce on which the ball is rolling?
Yes, the speed of a ball rolling down a ramp can change with the type of surface it is rolling on due to factors such as friction. A smoother surface will likely have less friction, allowing the ball to roll faster, while a rough surface will create more friction, slowing the ball down.
Is it true that rolling a cart up a ramp is an example of doing negative work?
No, rolling a cart up a ramp is an example of doing positive work, as energy is being transferred to the cart to lift it against gravity. Negative work would be done if the cart were rolling down the ramp, as energy would be lost against gravity.
True or false Rolling a cart up a ramp is an example of doing negative work?
False. ApEx C;
Cart is rolling down a special ramp where there is no friction at all What will happen if the amount of mass on the cart is increased?
If the mass of the cart is increased, the kinetic energy of the cart will also increase as it rolls down the ramp. The velocity of the cart will increase as well, since the kinetic energy is directly proportional to both mass and velocity squared.
What are the forces that act in an opposite direction to the motion of a cart?
Frictional forces, such as rolling resistance and air resistance, act in an opposite direction to the motion of a cart. These forces create resistance that opposes the cart's forward motion and can slow it down.
A ball rolling down an incline has its minimum speed?
The minimum speed of a ball rolling down an incline occurs when all its initial potential energy at the top of the incline is converted to kinetic energy at the bottom, without any loss to friction or other factors. This minimum speed can be calculated using the principle of conservation of energy.
A cart is rolling down a ramp if the angle of the ramp is increased to make the ramp steeper the cart will do what?
If the angle of the ramp is increased to make it steeper, the cart will accelerate more quickly down the ramp due to the increased gravitational force acting on it. The steeper ramp will result in a greater component of the gravitational force pulling the cart downhill, causing it to move faster.
What if The force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp?
If the force of friction acting on a cart on a ramp is exactly balanced by the force of gravity acting on the cart down the ramp, the cart will remain at a constant speed and not accelerate. This is an example of a state of equilibrium where the forces are balanced, resulting in no net force acting on the cart.
Is a longer tube better for rolling speed?
Yes because it is just like a ball rolling down a hill; it obviously goes faster.
What are the primary uses of rolling utility carts?
The rolling utility cart comes in the unique flavors of quarks: up, down, love, etc. One must try them to experience the awesome subatomic flavors in each bite.
Why a cart moving in rough road lower its speed?
A cart moving on a rough road experiences more friction between its wheels and the uneven surface, which causes energy loss and slows it down. The irregularities on the rough road create additional resistance that the cart must overcome, reducing its speed.
