What is the net force acting on the ball?
In the absence of any air resistance the only force acting on the ball is gravity.
Gravity slows the ball down when going up, and, speeds the ball up when coming down.
At the top of its path, gravity is still acting — there is a net downward force and the ball is not in equilibrium even though the speed is zero..
What if Newton’s third law didn’t exist?
Without the third laws existence you could not walk. For every action there is an equal and opposite reaction. Suppose the action is that you push on the ground with your foot, there would be no reaction to push you forward.
How much force is the student exerting on the rope in what direction?
Answer. Explanation: The physics student is tugging on the rope which he exerts 500 N from the illustration and it’s coming towards the student in the west direction which is left.
In which direction can a force be exerted on an object?
Natural force is the force exerted by the surface on the object. It is normal because the direction of the contact force is perpendicular to the surface, and normal has a meaning perpendicular.
Why does a rope climber pull downward?
The force that attracts earth to an object is equal and opposite the force that earth exerts on an object. … As the climber exerts a force downward, the rope supplies a reaction force that is directed upward. When the reaction force is greater than the climber’s weight, the climber accelerated upward.
What are the 10 types of forces?
Action-at-a-Distance ForcesApplied Force.Gravitational Force.Normal Force.Frictional Force.Air Resistance Force.Tension Force.Spring Force.
How does force affect acceleration?
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
What two variables is acceleration depend on?
The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object. The acceleration is always in the same direction as the net force.
What are the four main types of forces?
The Four Fundamental Forces of NatureGravity.The weak force.Electromagnetism.The strong force.
What if I push an object which is already moving horizontally?
Wouldn’t its velocity change and cause. be the result of a vertical force on the body. …
What object has the most inertia?
The smaller the inertia (mass) of an object, the less force is needed to accelerate it at a given rate. Since inertia is simply just a measurement of mass, the bowling ball has a higher mass, thus inertia, than the tennis ball.
What are the forces present on the rope answers?
Answer. Answer: The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T.
What is required to cause acceleration?
Acceleration is produced by a net force on an object and is directly proportional to the magnitude of the force, in the same direction as the force, and is inversely proportional to the mass of the object.
What force does the floor exert on you?
A: Newton’s third law states that every action has an equal and oposite reaction. You may not think this, but when you’re standing ont he floor, you are excerting a force against the floor: your weight, caused by gravity, is pulling you down. The floor is reacting by pushing back: we call this force the reaction force.
What happens if there is no tension on objects like a rope or a string?
Answer: the force of gravity is pulling the mass downward. However, the mass is not falling as it would if there were no string to hold it up. When objects are static, or not moving, the forces on them must be balanced.
What is tensional force?
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
What is the net force if you start to pull instead of pushing?
What is the net force if you start to pull instead of pushing in #6? An object will continue in its state of motion unless an unbalanced force is acting on it. If forces are balanced, then the net force equals 0. This means that there is no acceleration.
Did the wall exert a force on you?
It may surprise you to learn that if you push on a wall, the wall also pushes on you. According to Newton’s third law of motion, forces always act in equal but opposite pairs. … This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
