|
|
What factors change density of an object? |
Temperature, pressure and change of state |
|
|
What happens to density when you half the volume? |
Nothing because density depends on the material of the object as it is an intensive property |
|
|
What affects acceleration of gravity? |
Distance from earth surface & mass of object |
|
|
What happens when u increase height between object and surface of earth? |
Acceleration rate increases but g remains constant |
|
|
What factors effect coefficient of static friction (us) ? |
Nature of two surfaces |
|
|
Does the increase of angle of inclination affect coefficient of static friction (us) |
No |
|
|
Does mass affect coefficient of static friction |
No (only nature of material does) |
|
|
What factors affect spring constant (k) and its effective mass? |
Factors affecting (k): 1.Wire diameter: The diameter of the wire of the spring 2. Coil diameter: The diameters of the coils, depending on the stiffness of the spring. 3. Free length: Length of the spring from equilibrium at rest. Length decrease-> k increase 4. The number of active coils: The number of coils that compress or stretch. 5.Material: Material of the spring used to manufacture.
Effective mass of spring = 1/3 spring mass |
|
|
What happens to (k) and period of oscillation (T) when hanged mass is increased? |
Period of oscillation (T) is directly proportional to mass, and inversely proportional to (k) . Spring constant isn’t affected by mass |
|
|
Would frequency of oscillation change at the moon? |
No bc frequency of oscillation isn’t affected by gravity |
|
|
If air resistance is neglected , and two objects with different masses are dropped at same height would they land at the same time? |
Yes |
|
|
Do all motions in straight line have constant acceleration ? |
No |
|
|
What’s the angle of projection that gives the maximum range attainable by a projectile? |
45 |
|
|
Would increasing mass of object increase friction force? |
Yes |
