How does a surface affect the movement of an object?
Friction is the contact force between two objects moving against each other; the kind of surface that objects have affects how objects move against each other. The greater the force is, the greater the change in motion will be. • Students may believe the surface on which an object moves does not affect its motion.
How does surface affect force?
The force due to friction is generally independent of the contact area between the two surfaces. But when you double the length of an object, you halve the force on each square centimeter, because less weight is above it to push down.
How does the surface of an object affect friction?
Friction is a force that opposes motion between any surfaces that are touching. Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force.
How does the surface affect speed?
The makeup of the two surfaces in contact has a great affect on the amount of friction. So, the short answer to your question is yes, if you change the surface that the ball rolls down, the ball’s speed will change.
What causes movement of an object?
For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Not all forces cause motion, however. Some forces, like gravity and friction, resist or work against movement.
What surface has the most friction?
From our experiments, we have concluded that the rougher surfaces have a higher coefficient of friction. The highest was sandpaper which had a average coefficient of friction of 1.666. Next was foil, with an average coefficient of friction 1.665. After that, it was felt with a average coefficient of friction of 1.645.
What is surface friction?
Resistance to movement of air flowing along the surface of the earth or other surface such as an airplane wing. In the atmosphere, surface friction is related to turbulent drag. Compare friction velocity, drag coefficient, Reynolds stress.
How does the surface of the ground affect how far a ball will roll?
Rolling friction is affected by the texture of both the surface and the rolling object. Had I used a tennis ball it probably would have rolled a shorter distance because of the ball’s texture. Conclusion: The marble rolled farther on smoother textures, with texture clearly affecting the distance traveled.
