When a cannon is fired Why does the cannonball move so much more than the cannon?
Newton’s third law states that for every action there must be an equal and opposite reaction, so the forces on the cannon and cannonball are equal in magnitude (but not direction). and the mass of the cannon is larger than the mass of the cannonball, so the acceleration is lesser for the cannon than for the cannonball.
When a cannonball is fired from a cannon the cannon will slightly roll backwards which of Newton’s laws of motion best explains why this occurs?
Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon gains backward momentum. Before the cannon is fired (the ‘event’) the total momentum is zero.
How does the magnitude of acceleration of the rifle compare with the magnitude of acceleration of the bullet and why?
The magnitude of acceleration of the rifle is equal to the magnitude of acceleration of the bullet because they experience the same magnitude of force.
How does the magnitude of the vertical component of velocity for a ball tossed?
How does the magnitude of the vertical component of velocity for a ball tossed at an upward angle change as the ball travels upward? The vertical component decreases in magnitude until it reaches the maximum height and then increases; the horizontal component is constant.
Why do the cannonball and cannon have very different acceleration?
The cannonball undergoes more acceleration than the cannon because its mass is much smaller. Interestingly enough, in the interaction between the boulder and Earth, shown in Figure 7.6, the boulder pulls up on Earth with as much force as Earth pulls down on the boulder.
When a cannonball is fired from a cannon the force the cannon exerts on the cannonball is exactly?
Because Earth has a huge mass, we don’t sense its small acceleration. When a cannon is fired, there is an interaction between the cannon and the cannonball. The force the cannon exerts on the cannonball is exactly equal and opposite to the force the cannonball exerts on the cannon.
When a cannon fires a cannonball?
When a cannon fires a cannonball, the cannon will recoil backward because the momentum of the cannon is greater than the energy of the cannonball. energy of the cannonball and cannon is conserved. energy of the cannon is greater than the energy of the cannonball. momentum of the cannonball and cannon is conserved.
Why does a cannon recoil when it fires a cannonball momentum?
In terms of momentum conservation, why does a cannon recoil when fired? The cannon must recoil in order for momentum to be conserved. (The momentum of the cannon–cannonball system was zero before the firing, and must remain zero after the firing.)
What does it say about mass and 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.
Which is more important in winning in a tug of war?
There are 6 forces exerted. Which is most important in winning in a tug-of-war; pulling harder on the rope, or pushing harder on the floor? Pushing harder on the floor. The paper isn’t capable of exerting a reaction force.
When you push against a wall with your fingers they bend?
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. When you push against a wall with your fingers, they bend because they experience a force.
When you push on a wall What pushes back on you?
The acceleration of the wall is zero because the net force on the wall is zero. When you push on a wall with a force F, the wall pushes back on you with and equal and opposite force F per Newton’s third law.
When a ball falls downward it may have a net force group of answer choices?
Terms in this set (19) When a ball falls downward, it may have a net force: of zero.
Can you physically touch a person without?
No, one cannot physically touch a person without that person touching him with the same amount of force. This is because there will be Newton’s
Why doesn’t a heavy object accelerate more than a light object when both are freely falling?
Why doesn’t a heavy object accelerate more than a lighter object when both are freely falling? o Because the greater mass offsets the equally greater force; whereas force tends to accelerate things, mass tends to resist acceleration.
