Newton's Laws of Motion
How could you infer that subatomic particle interactions are relevant when calculating contact forces between two colliding soccer balls?
Equal and opposite reaction seen on a large scale implies irrelevant subatomic particle influence during physical ball interactions.
Macrolevel observations of ball trajectories after collision meet classical expectations regardless of underlying particle behaviors.
Constant acceleration prior to collision demonstrated visible evidence of traditional Newtonian physics sufficing to explain the phenomenon.
Observation of microscopic deformations upon impact suggests underlying atomic structures influencing overall collision mechanics.
Which of Newton's laws explains why a satellite in orbit continues to move around Earth without propulsion?
None of these laws apply to satellites in orbit.
Newtonโs first law โ an object in motion stays in motion with a constant velocity unless acted upon by an unbalanced force.
Newtonโs third law โ for every action there is an equal and opposite reaction.
Newtonโs second law โ force equals mass times acceleration.
A ball is tethered to a pole by a string and moves in a horizontal circle at constant speed; what happens to the tension in the string if the speed of the ball doubles?
The tension quadruples.
The tension halves.
The tension remains unchanged.
The tension doubles.
What does Newtonโs third law of motion state?
Force equals mass times acceleration.
The acceleration of an object is directly proportional to the net external force acting on it and inversely proportional to its mass.
For every action, there is an equal and opposite reaction.
An object at rest stays at rest unless acted upon by an outside force.
By integrating an object's acceleration function with respect to time, you obtain the object's _______.
Position function
Force applied
Velocity function
Displacement
If an object of mass m is initially at rest on a frictionless surface and a horizontal force F is applied for a time t, which scenario results in the greatest final momentum for the object based on Newton's second law?
A force that oscillates sinusoidally with a maximum value of F during the time interval t is applied.
A force that decreases linearly from F to 0 over the time interval t is applied.
A single constant force F is applied throughout the time interval t.
A force that increases linearly from 0 to F over the time interval t is applied.
Question #5: In a system where a block of mass is attached to a string that is wrapped around a pulley without slippage and then connected to a second identical block, but this one is partially submerged in water, what impact would in...
Increasing the density of water would have little to no effect on the system's equilibrium because the buoyant force already balances gravity for the submerged block.
Increasing the density of water would cause the system to tilt, thus tilting the pulley and making it unstable.
Increasing the density of the water would cause the first block to sink further due to increased buoyant force on the second.
Increasing the density of water would raise the second block slightly until a new equilibrium is established.
