Description
"The Movement of Cars" Toys Around You PPT Courseware 2
The relationship between the speed of the car's movement and the magnitude of the push and pull forces
Experimental equipment: timer, trolley, ruler, hook code, cotton thread.
experiment procedure:
1. Use the pulling force of 1 hook code to test the time it takes for the trolley to travel a distance of 90 cm.
2. Use the pulling force of 3 hook codes to test the time it takes for the trolley to travel a distance of 90 cm.
3. Use the pulling force of 5 hook codes to test the time it takes for the trolley to travel a distance of 90 cm.
Notes: The team has a clear division of labor and good observation records. Each set of experiments was performed at least three times to ensure the accuracy of the experiment.
The relationship between the speed of the car and the pulling force
The car maintains a certain weight, and the speed of the car's movement is related to its power: the greater the power, the faster it moves, and the smaller the power, the slower it moves.
The relationship between the speed of the trolley and the load
●Under a certain power, the movement speed of the trolley is related to the load capacity of the trolley: the greater the load capacity, the slower the movement speed.
●The load capacity of the trolley is also related to the force that changes its motion state: the greater the load capacity of the trolley, the greater the force to start the trolley, and the greater the force to prevent the movement of the trolley.
The relationship between the motion of the car and friction
Under the condition that the car maintains a certain power and weight: the greater the friction, the slower the car moves; the smaller the friction, the faster the car moves.
Different methods can be used to friction or reduce friction according to different needs. For example: changing the size of the contact surface, changing the smoothness of the contact surface, changing the movement of the object, etc.
What is the relationship between the movement of the car and
The forces that make the car move: gravity, elastic force, reaction force and recoil force.
Some factors that affect the movement of the car: power, weight of the car and friction.
