Grundet at tyngdekraften er en milliard gange svagere end de andre vekselvirkninger. Tyngdekraften er derimod utrolig betydningsfuld på større områder som fx vores jordklode. Det er også tyngdekraften, som styrer planeternes bevægelse. Man kan på vores jordklode mærke tyngdekraften stærkere end på nogle andre planeter fx Mars. Tyngdekraften er svingende over jordens areal. Dette kan ses på billedet.
