ViviTrial and error method involves repeatedly trying different solutions until one is successful. It is often used in problem-solving when the correct solution is not immediately apparent, allowing for exploration of various approaches to achieve the desired result. This method is iterative and may involve making mistakes before finding the right solution.

Heat is transferred by conduction when it's moving am molecules bump into its moving molecules and transfer it energy?
Conduction is a method of heat transfer where heat flows through a material due to direct contact between its molecules. When a material is heated, its molecules vibrate and collide with neighboring molecules, transferring thermal energy in the process. This transfer continues until the material reaches thermal equilibrium.
Why do you push harder on the pedals of the bicycle when first starting out than when moving at constant speed?
When starting out on a bicycle, you need to overcome inertia to get the wheels moving. This requires more force to accelerate the mass of the bike and rider. Once in motion, maintaining a constant speed requires less force because you are overcoming friction and air resistance, which are lower once the bike is moving.
What force can start a moving object?
An external force, such as a push or a pull, can start a moving object by overcoming its inertia and setting it in motion. Once the object is in motion, it will continue moving until acted upon by another force.
Why does the ball stop moving?
The ball stops moving due to forces such as friction and air resistance acting upon it, slowing it down until it comes to a complete stop. Additionally, external factors such as hitting a wall or surface can also cause the ball to stop moving.
IS THE FRICTIONAL FORCE THAT ACTS ON OBJECTS THAT ARE NOT MOVING?
Yes, the frictional force acts on objects that are not moving, opposing the motion that would occur if there were no friction present. This static friction force prevents the object from moving until a force greater than the static friction force is applied.
