What is the formula for Newton's second law of motion?
Click to flip
The formula is F = ma, where F is force, m is mass, and a is acceleration.
Click to flip
In Newton's second law, what does the variable 'F' represent?
Click to flip
'F' represents force, measured in newtons (N).
Click to flip
What does the variable 'm' stand for in Newton's second law?
Click to flip
'm' stands for mass, which is the amount of matter in an object and typically measured in kilograms (kg).
Click to flip
What does the variable 'a' indicate in the equation F = ma?
Click to flip
'a' indicates acceleration, the rate of change of velocity, measured in meters per second squared (m/s²).
Click to flip
How does increasing mass affect acceleration in Newton's second law if the force is constant?
Click to flip
If the force is constant, increasing the mass will decrease the acceleration.
Click to flip
If a car accelerates at 3 m/s² with a 1000 kg mass, what is the force applied?
Click to flip
The force applied would be F = ma = 1000 kg * 3 m/s² = 3000 N.
Click to flip
Describe the relationship between force and acceleration according to Newton's second law.
Click to flip
Force is directly proportional to acceleration when the mass is constant.
Click to flip
What kind of quantity is force and why?
Click to flip
Force is a vector quantity because it has both magnitude and direction.
Click to flip
If you double the force applied to an object, how does it affect the acceleration, assuming mass is constant?
Click to flip
Doubling the force will double the acceleration.
Click to flip
What unit is force measured in?
Click to flip
Force is measured in newtons (N).
Click to flip
How would the acceleration change if the mass is halved, assuming a constant force?
Click to flip
The acceleration would double if the mass is halved while force is constant.
Click to flip
What is required to change the velocity of an object, according to Newton's second law?
Click to flip
An unbalanced force is required to change the velocity of an object.
Click to flip
In Newton's second law, what happens if no net force acts on an object?
Click to flip
If no net force acts, the object remains in its current state of motion (at rest or in uniform motion).
Click to flip
What happens to acceleration if both the force and mass are doubled?
Click to flip
The acceleration remains the same since both force and mass are doubled, canceling each other out in their proportional effect.
Click to flip
Why is Newton's second law important in understanding motion?
Click to flip
It's important because it quantitatively describes how forces influence motion, allowing predictions about the behavior of moving objects.
