Unformatted text preview: arth's surface is F = 100 kg 9.8 m/s2 = 980 Newtons. (An apple weighs about 2 N, a golf ball weighs 1.4 N) Spring 2008 9 UCSD Physics 10 Said Another Way.... Gravitational force is proportional to mass F = ma gives an object's responding acceleration Divide both sides of the equation by "m" a = F/m Both numerator and denominator are proportional to "m", if force is gravity SO....acceleration is the same, regardless of the mass We'll return to this point when we consider General Relativity! Spring 2008 10 UCSD Physics 10 Falling Objects Accelerate Ignoring air resistance, falling objects near the surface of the Earth experience a constant acceleration of 9.8 m/s2. That means if you drop something it goes faster and faster, increasing its speed downwards by 9.8 m/s in each passing second. Spring 2008 11 UCSD Physics 10 Gravitational Force is Acting All the Time! Consider a tossed ball.... Does gravity ever switch off? As a ball travels in an arc, does the gravitational for...
