Go to the roller coaster simulation and click on the "launch" button. pay attention to the pie chart as the roller coaster moves and fill in the blank. be sure to keep this website open because there will be several questions related to it.

the kinetic energy the roller coaster goes downhill.

click the "step" button on the simulation to observe the energy at different points on the roller coaster ride.

kinetic energy is greatest
potential energy is greatest at
kinetic energy is decreasing while potential energy is increasing between

which chart comes closest to the relationship between kinetic energy and potential energy at point 6?
increases
point 2
point 1
3 and 4
the middle one

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.
