Force & Mass: Calculating Acceleration

In summary, the conversation discusses the relationship between net force, mass, and acceleration. It is stated that a net force F causes an object with a mass of m to have an acceleration of 9.70 m/s/s. When the mass is increased by a factor of 7.0, the new acceleration remains the same. This is because mass does not affect acceleration in a constant force system. The formula fnet=MA is mentioned but the exact interpretation is unclear. The conversation ends with a hint that the problem is simple and involves finding the new acceleration when the mass is increased by a factor of 7.0.

Homework Statement



Suppose that a net force F gives an object with a mass of m an acceleration of 9.70 m/s/s.

Suppose that the mass were increased by a factor of 7.0. The new acceleration would be ___ m/s/s

Homework Equations



fnet=Mass*acceleration

The Attempt at a Solution



well i know that fnet=MA is the formula to use but don't know how to interperet it if a factor changes

thanks :)

Mass does not effect acceleration.

Hint: its a very simple problem.

This is not true at all.

If the force is constant, and your new m' = 7m, what must a' = so that the force remains hte same?
 

1. What is force and how is it related to mass and acceleration?

Force is a physical quantity that can change the state of motion of an object. It is related to mass and acceleration through Newton's second law, which states that force is equal to mass times acceleration (F=ma).

2. How do you calculate acceleration when given force and mass?

To calculate acceleration, you can use the equation a=F/m, where a is acceleration, F is force, and m is mass. Simply plug in the given values for force and mass and solve for acceleration.

3. Can you have acceleration without force?

No, acceleration cannot occur without a force acting on an object. In the absence of a force, an object will either remain at rest or continue moving at a constant velocity.

4. How does the mass of an object affect its acceleration?

The mass of an object has an inverse relationship with its acceleration. This means that as the mass of an object increases, its acceleration decreases. This can be seen in Newton's second law, where acceleration is inversely proportional to mass.

5. What are some real-life examples of force and mass affecting acceleration?

Some examples of force and mass affecting acceleration can be seen in everyday activities such as pushing a shopping cart (where the force of your push affects the acceleration of the cart), throwing a ball (where the mass of the ball affects its acceleration), or driving a car (where the engine's force affects the car's acceleration).
