what is the value of work done on an object when a 0.1x102-newton force moves it 30 meters and the angle between the force and the
displacement is 25°?

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

Why are graphs useful when interpreting data

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight
