Answer:
Aristotle believed that matter was made of tiny particles.
Explanation:
''Aristotle vehemently opposed the Atomic theory developed by Democritus. He believed that instead of being matter being made of tiny particles (atoms) that they were all fundamentally air, fire, water, and earth.''
Answer:
You will feel more weight if it is accelerating out of the planet.
You will feel less weight if it is accelerating towards the planet.
Explanation:
The weight that you are observing or feeling is basically due to the change in acceleration of your fall or rising up in the spaceship. When the acceleration is stationary on the surface, you experience your normal weight due to the gravitational acceleration of that planet.
When the spaceship accelerates above or out of the planet you experience acceleration more than the acceleration of gravity hence more weight.
When the spaceship accelerates towards the planet you experience acceleration less than the acceleration of gravity hence less weight.
If the spaceship is free falling at the gravitational acceleration you experience a zero weight
Answer: A. It can only be motionless.
Explanation: When balanced forces act on an object, the object will not move. The only way that object can move is if the forces become unbalanced. Suppose there is a shoe on a table. You are pulling back on the shoe with a force of 3 newtons. But the friction from the shoe rubbing on the table is also 3 newtons of force. But the gravity pulling down on the shoe is also 3 newtons. Nothing will move. The only way the shoe can move is if you pulled with a little more force. The shoe would then move because the force you are pulling with is greater than the other forces acting on the shoe.
Ex 2: You are playing tug of war. Team a is pulling with 20 Newtons of force. Team b is also pulling with 20 newtons of force. The rope does not move. Team a starts to pull a little harder. Now they are pulling with 25 Newtons of force. Now the rope starts moving their way.
