10 Questions
What is the force that opposes motion between two surfaces in contact?
Frictional force
What is the type of friction that occurs when an object is stationary and is subjected to an external force?
Static friction
What is the force that acts perpendicular to the surface and is responsible for the normal contact between two surfaces?
Normal force
What is the type of friction that occurs when an object is moving and is subjected to an external force?
Kinetic friction
What is the force that acts along the surface and is responsible for the frictional force between two surfaces?
Tangential force
Match the types of friction with their descriptions:
Static friction = Friction that occurs when an object is stationary and is subjected to an external force Kinetic friction = Friction that occurs when an object is moving and is subjected to an external force Rolling friction = Friction that occurs when an object is rolling on a surface Fluid friction = Friction that occurs when an object is moving through a fluid
Match the forces with their effects:
Normal force = Acts perpendicular to the surface and is responsible for the normal contact between two surfaces Frictional force = Acts along the surface and is responsible for the frictional force between two surfaces Applied force = Causes an object to accelerate Gravity = Attracts objects towards each other
Match the types of surfaces with their effects on friction:
Smooth surface = Reduces frictional force Rough surface = Increases frictional force Inclined surface = Changes the direction of the normal force Horizontal surface = Does not change the direction of the normal force
Match the effects of friction with their descriptions:
Heat generation = Heat produced due to friction Wear and tear = Damage to surfaces due to friction Energy loss = Energy lost due to friction Sound production = Sound produced due to friction
Match the factors with their effects on friction:
Surface area = Increases frictional force Normal force = Increases frictional force Surface roughness = Increases frictional force Velocity = Decreases frictional force
Study Notes
Since the text is "Generate a exam for me class 9 physics carvan books house chapter 6 and e", I'm assuming you want study notes for Class 9 Physics, Carvan Books House, Chapter 6 (Motion and Time) and possibly Chapter E (not specified). Here are the notes:
Motion
- Motion is a change in the position of an object over time
- It can be described in terms of distance, displacement, speed, velocity, and acceleration
Types of Motion
- Rectilinear motion: motion along a straight line
- Circular motion: motion in a circular path
- Oscillatory motion: repetitive back-and-forth motion
Distance and Displacement
- Distance: total length of the path travelled by an object
- Displacement: shortest distance between initial and final positions
Speed and Velocity
- Speed: distance travelled per unit time
- Velocity: displacement per unit time
- Velocity is a vector quantity, having both magnitude and direction
Acceleration
- Acceleration: change in velocity per unit time
- It is a vector quantity, having both magnitude and direction
- SI unit of acceleration is m/s²
Graphical Representation of Motion
- Distance-time graph: a straight line represents uniform motion
- Velocity-time graph: a straight line represents uniform acceleration
- Acceleration-time graph: a straight line represents uniform change in acceleration
