Mass and Acceleration Relationship
According to Newton's Second Law, what happens to an object's acceleration if the mass increases while the force remains constant?
The acceleration decreases.
Question: A 5 kg object experiences a force of 10 N. What is its acceleration?
2 m/s²
Question: What is the formula for Newton's Second Law of Motion?
F = ma
Provide an everyday example where Newton's Second Law can be observed.
Pushing a sled to make it move
An object with a mass of 8 kg has an acceleration of 2 m/s². Calculate the force acting on it.
16 N
If an object has a mass of 2 kg and an acceleration of 6 m/s², what is the force acting on it?
12 N
How does a rocket taking off into space illustrate Newton's Second Law?
The rocket expels high-speed exhaust gases, creating a forward force that propels it in the opposite direction.
A 10 N force is applied to an object, resulting in an acceleration of 5 m/s². Calculate the mass of the object.
2 kg
How does Newton's Second Law explain the behavior of a car when you press the gas pedal?
The applied force accelerates the car, following F = ma.
If the mass of an object is doubled while the force remains the same, how does the acceleration change
The acceleration is halved.
Explain how a parachute works using Newton's Second Law.
A parachute increases air resistance, slowing down the descent of the person and reducing the net force.
If an object experiences a force of 40 N and accelerates at 8 m/s², what is its mass?
5 kg
If the mass of an object is 4 kg, and you want it to accelerate at 5 m/s², how much force do you need to apply?
20 N
If the force applied to an object is increased while keeping the mass constant, what happens to the acceleration?
The acceleration increases
If you're trying to push a heavy cart, how does Newton's Second Law relate to the effort needed to get it moving?
You need to apply a sufficient force to accelerate the cart due to its mass.
A 3 kg object experiences an acceleration of 4 m/s². Calculate the force acting on it.
12 N
In terms of Newton's Second Law, what does it mean when you say that force and acceleration are directly proportional?
It means that increasing force leads to a proportional increase in acceleration, assuming mass remains constant.
