Apple held in hand.
According to Newton's First Law, It is at rest, thus there is no net force.
srength of resultant force = 0N
Apple falling to the ground.
According to Newton's Second law,
The object will accelerate in the direction of force applied. Hence its downwards.
Strength of resultant force = 2N
Apple moving upwards.
According to Newtons Second law,
(same as above) upwards.
Strength undefined.

What is the use of weight sets?
Weight sets are used for strength training and muscle building. They provide varying levels of resistance that can be adjusted to suit different fitness levels and goals. By using weight sets, individuals can target specific muscle groups and increase their overall strength and endurance.
When you are at rest and supported by a pair of weighing scales how does the sum of the scale readings compare with you weight?
When you are at rest and supported by a pair of weighing scales, the sum of the scale readings will equal your weight. This is because the scales are each measuring a component of your weight in the vertical direction.
Steps for weighing an object?
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
What is the maximum dumbbell weight that can be safely lifted by beginners?
For beginners, it is generally safe to start with dumbbells weighing between 5 to 15 pounds to avoid injury and build strength gradually.
How much weight can a 2 pound magnet lift?
The lifting capacity of a magnet depends on its strength and the material it is attracting. Generally, a 2-pound magnet can lift objects weighing up to 2 pounds, but this may vary depending on the surface area and magnetic strength of the magnet.
Is it said weighing a cake or scaling a cake?
Weighing (US)
Which is more accurate direct weighing or weighing by difference?
Weighing by difference is generally more accurate than direct weighing because it accounts for any loss of material during the weighing process. Direct weighing can be influenced by factors like measurement errors or environmental conditions, which may affect the accuracy of the result.
What is air resistance reduced by?
Air resistance is reduced by the streamlined of shapes. Because for eg. if you have two cars both weighing the same but their shape in the front are different the one with the sharper point will go faster and reduce fuel.
How do weighing scales measure body fat accurately?
Weighing scales that measure body fat accurately use a method called bioelectrical impedance analysis (BIA). BIA sends a small electrical current through the body to measure the resistance of different tissues, such as fat and muscle. This information is then used to calculate the percentage of body fat.
What is the work done by a person in carrying a suitcase weighing 10kgf on his head when he travels a distance of 5m in the vertical and horizontal direction?
The work done by the person is zero in the horizontal direction because the force and displacement are perpendicular. In the vertical direction, the work done is 10kgf * 9.8m/s^2 * 5m = 490 Joules, as the force of gravity acts against the displacement.
Why will a rock and feather land on the ground at the same time?
They won't. Two nearly identical objects (equal-sized cubes for example) will land at the same time as long as they are heavy enough to overcome wind resistance. If you have a ten-pound ball and a twenty-pound ball, they will hit the ground at the same time. However, if you had a ball weighing less than an ounce and one weighing a pound, of course they will not hit the ground at the same time: the ball weighing less than an ounce wouldn't fall - it would be affected enough by wind resistance to slow down. If there was no air, the feather and the rock will hit the ground at the same time. Factoid.
How heavy is a weighing scale?
A weighing scale itself is not heavy, as it is designed to be easily movable and transportable. The weight of a weighing scale can vary depending on the type and size, but typically they are lightweight and can be easily carried by hand.
