18 Questions
What can be inferred about the relationship between forces and motion from the given text?
Forces can change the magnitude of velocity of an object
Why does a box not move when a small force is applied to push it?
Friction balances the pushing force
What happens when the pushing force applied to a box becomes bigger than the friction force?
An unbalanced force causes the box to start moving
Which action does NOT change the state of motion of an object?
Staring
What role does friction play in preventing motion?
Friction balances the pushing force
In Fig. 9.4(c), what condition leads to the box starting to move?
An unbalanced force is created
What concept is based on push, hit, or pull according to the text?
Force
Why does the speed of an object change with time based on the text?
Due to the application of force
Who introduced an entirely different approach to understand motion according to the text?
Galileo Galilei and Isaac Newton
What is considered the 'natural state' of an object based on observations in the text?
Rest
What do we always see or feel according to the text?
The effect of force
What is the concept that describes the motion of an object along a straight line according to the text?
'Position, Velocity, and Acceleration'
What does the negative sign imply about the frictional force exerted by the table?
It is opposite to the motion of the ball
According to the third law of motion, how are the forces exerted between two objects?
Equal in magnitude and opposite direction
In the context of action and reaction forces, what happens when two players collide during a football game?
Both players feel hurt because they both apply a force to each other
What do the spring balances connected together in Fig. 9.10 show when a force is applied?
The same readings on their scales
How are action and reaction forces described in relation to each other?
They are equal in magnitude and opposite in direction
When one object exerts a force on another, what term refers to these forces?
Action and reaction forces
This quiz covers the basic concepts of force and motion, including how different forces can affect objects in terms of velocity, direction, shape, and size. It also explores common actions such as pushing, hitting, and pulling that result in object motion.
