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

400

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

400

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.
