Gravitational Fields and Forces
On this worksheet you will examine the properties of gravitational forces and fields.
Two masses, 3 kg and 6 kg, initially at rest, are both released and fall freely to the ground. Which mass would experience the greater acceleration while falling?
both masses experience the same acceleration
When initially released, which mass experienced the greater gravitational force of attraction to the earth?
both masses experience the same gravitational force of attraction
When initially released, which mass weighed more in the earth's gravitational field?
both masses weighed the same
If when both masses impact the earth their centers land 2.964 meters apart, what is the gravitational force exerted on the small mass by the larger mass?
1.37 x 10
2.28 x 10
6.83 x 10
1.52 x 10
On the surface of Planet X a 38-kg mass weighs 744.8 N. What is the local value of Planet X's gravitational field strength?
If Planet X has the same radius as the Earth, what is the mass of Planet X? If needed, the mass of the Earth is 5.98 x 10
1.17 x 10
1.15 x 10
2.99 x 10
1.2 x 10
If the 38-kg mass is moved to a position which is 7.8 radii above the surface of Planet X, how will its weight be affected?
its weight will be increased by a factor of 78 / 10
its weight will be increased by a factor of 6084 / 100
its weight will be decreased by a factor of 100 / 6084
its weight will be decreased by a factor of 10 / 78
When released from rest an object in freefall and tracked by a motion detector, which of the following position-time graphs will be displayed?
