QuestionWhich of the following statements is NOT true about gravitational forces? There are no repulsive gravitational forces. A thrown baseball follows orbital motion (neglecting air resistance), but the orbit intersects the Earth. Gravity is the strongest of the fundamental forces Any two particles in the universe exert attractive forces on each other. Submit Answer
Studdy Solution
STEP 1
1. We are analyzing statements about gravitational forces.
2. We need to identify the statement that is NOT true.
STEP 2
1. Review each statement about gravitational forces.
2. Determine the truthfulness of each statement.
3. Identify the statement that is NOT true.
STEP 3
Review the statement: "There are no repulsive gravitational forces."
Gravitational forces are always attractive; there are no known repulsive gravitational forces.
STEP 4
Review the statement: "A thrown baseball follows orbital motion (neglecting air resistance), but the orbit intersects the Earth."
A thrown baseball follows a parabolic trajectory, which can be considered a segment of an elliptical orbit with the Earth at one focus. Thus, this statement is true.
STEP 5
Review the statement: "Gravity is the strongest of the fundamental forces."
Gravity is actually the weakest of the four fundamental forces (gravity, electromagnetism, strong nuclear, and weak nuclear).
STEP 6
Review the statement: "Any two particles in the universe exert attractive forces on each other."
According to Newton's law of universal gravitation, any two particles with mass exert an attractive force on each other.
STEP 7
Determine the truthfulness of each statement.
The statement "Gravity is the strongest of the fundamental forces" is NOT true.
The statement that is NOT true is:
