Which of the following is true about the relationship between mass and gravitational force?

Greater distance results in smaller force.

Smaller distance results greater force.

Smaller mass results in greater force.

Greater mass results in greater force.

For a particular reaction, ? h = -144.6 kj and ? s = -301.2 j/k. calculate ? g for this reaction at 298 k.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
