Why does lifting need more force than pulling?
Lifting an object against gravity requires more force than pulling it along a horizontal surface because you are working against the force of gravity. When lifting, you are fighting against the weight of the object in addition to any other resistance present, such as friction. Pulling, on the other hand, only requires overcoming the frictional force.
How much work is done when a 195g tomato is lifted 19.4m?
The work done lifting the tomato against gravity is calculated as the product of its weight (force due to gravity) and the vertical distance it is lifted. The weight of the tomato is 195g * 9.81 m/sĀ² = 1.91 N. Therefore, the work done lifting the tomato is 1.91 N * 19.4 m = 37.03 Joules.
Lift something against gravity and you're measuring its?
Lift something against gravity and you're measuring its weight, which is the force acting on it due to gravity.
Do you usually gain or lose weight lifting weights?
This depends on the person and the kind of weight lifting you do. The short answer however is that lifting weights should help you to lose fat and gain muscle. If you are lifting heavily in order to gain muscle mass, you will gain weight. However, if you are lifting to get lean muscle, it should help to lose weight.
Where should your center of gravity be when In a relationship to your base of support when lifting an object?
Your center of gravity should be directly above your base of support when lifting an object to maintain balance and stability. This alignment helps distribute the weight of the object effectively through your body, reducing the risk of injury. Keeping your center of gravity over your base of support also helps you control the movement of the object more efficiently.
What is a push and how is it different to a pull?
push= using ur weight against gravity/forcing weight agaisnt gravity pull=using strength to pull with/against gravity (sorry my answer isn't that great and scientific!)
Two individuals are lifting two hundred pounds how much weight is each individual lifting?
Assuming that each person is lifting equally the answer is 100 lbs each. The total weight 200, divided by 2. In reality it would depend on the center of gravity for the box, and also how evenly the weight of the box is distributed, plus also the height of the two lifters and the positions of their hands relative to the box's center of gravity.
If a barbell weight 160 N What other information do you need to calculate how much work it takes to lift it?
To calculate how much work it takes to lift the barbell, you will need to know the height you are lifting it to (distance over which the force is applied) and the angle at which you are lifting the barbell (if not directly against gravity). These factors will allow you to calculate the work done against gravity using the formula: Work = Force x Distance x cos(angle).
Why can you pull a garage door down easy after raising it?
When you raise a garage door, you are transferring potential energy to the system by lifting its weight against gravity. When you pull it down, you are releasing that potential energy. The counterbalance mechanism in the door helps to offset its weight, making it easier to bring down.
Is boxing weight lifting?
No, boxing is not weight lifting
Is lifting a dumbell isotonic or isometric?
Lifting a dumbbell is considered isotonic exercise because the muscle length changes as the weight is lifted against gravity. Isometric exercise, on the other hand, involves static muscle contractions without changing muscle length.
How would weight lifting be different on the moon compared to earth?
Weight lifting on the moon would be easier due to the moon's lower gravity, about 1/6th of Earth's gravity. This means weights would feel lighter and easier to lift. However, the lack of atmosphere and different environment would present challenges in terms of equipment stability and body adaptation.
