Is acceleration due to gravity act on a body resting on a table zero?
Yes, when an object is resting on a table, the acceleration due to gravity acts vertically downward, but the table exerts an equal and opposite force (normal force) on the object in the upward direction, canceling out the effect of gravity. Therefore, the net acceleration on the body is zero.
What is the definition of force in the 3 laws of motion?
for every force which act on one body action force there is an equal and opposite forces reaction force which act on same other body
When a body is falling freely which force act on it?
When a body is falling freely, the only force acting on it is gravity. This force causes the body to accelerate downwards at a rate of 9.81 m/s^2 near the surface of the Earth.
Which type of force can act through empty space?
Electric and gravitational force can act through "empty" space.
Do action and reaction act on same body?
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
What part of the body acts as the effort force?
Muscles in the body act as the effort force. When muscles contract, they generate force to move bones and produce movement in the body.
Does any force act on a body at rest?
Gravity, pressure.
How does your body use levers?
Your body uses levers to generate and transmit force for movements. Muscles act as the effort force, joints act as the fulcrum, and bones act as the rigid lever arms. By adjusting the position of these components, your body can produce a wide range of movements efficiently.
Does the buoyant force act in all ways?
No buoyant force would act only in the upward direction against the weight of the body as it gets immersed in the liquid.
What are the two forces that act together to keep a body in orbit around another body?
gravity and force
What direction does the force of friction act when a body slides?
In the direction opposite to that of the sliding body.
What forces act on still objects?
The main force acting on a still object is typically the force of gravity pulling it down towards the Earth. Other forces, such as friction and air resistance, may also act on the object depending on the surface it is resting on and the environment it is in.
