2 The greater the force applied on an object, the greater it's acceleration
3 You can find the mass of an object if you know it's acceleration and the forces acting on it
4 Force is equal to the product of mass and acceleration
Answer:
1. The mass will change depending on the force.
Explanation:
We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:
F = ma
Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.
In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa
Explanation:
Let be the airspeed.
Let be the cross wind speed.
We know that,ground speed is the vector sum of airspeed and cross wind speed and airspeed is perpendicular to cross wind speed.
If and are two perpendicular vectors,the resultant vector has the magnitude
Given,
So,the ground speed is
