15 Questions
What is the equation for Newton's second law of motion?
$F = ma$
What are the units for measuring acceleration?
Meters per second squared (m/s^{2})
What is the unit of measurement for the net force acting on an object?
Newtons (N)
According to Newton's second law of motion, what happens to an object when the net force acting on it is not equal to zero?
The object moves in a constant acceleration
What did Newton find the net force to be directly proportional to?
The change in momentum over a period
What is momentum defined as?
The product of an object's mass and velocity
What did Newton conclude the net force equals?
The object's mass multiplied by the change in the object's velocity over time
What is the mathematical expression for Newton's second law?
$F_{net} = ma$
In the experiment with the linear air track, what was the observed relationship between net force and acceleration?
The ratio of net force to acceleration was constant and equal to 10
What happens to the acceleration of an object if the net force acting on it is doubled while keeping the mass constant?
The acceleration doubles
If the mass of an object is doubled while keeping the net force constant, what happens to the acceleration?
The acceleration is halved
What is the formula to calculate acceleration using Newton's second law?
$a = \frac{F_{net}}{m}$
What does the slope of the graph of net force versus acceleration represent in the linear air track experiment?
The mass of the object
In the experiment with wind-up cars, what effect does friction have on the acceleration of the cars?
Friction reduces the net force and slows down the acceleration
What conclusion can be drawn from the experiment with wind-up cars when one car has a weight attached to it?
The car with the weight moves slower due to increased resistance from friction
