In the Exploration, the magnitudes of instantaneous velocity and instantaneous speed are always equal. Explain why the magnitudes of average velocity and average speed for a curved path are different.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

false

hope this : d

1. metals

2. metalloids only

3. nonmetals only

4. metals and metalloids

5. metalloids and nonmetals

i just took this assignment so this is correct
