When a cannon is fired are the forces?

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.

What forces act on a cannonball?

Viewing the cannonball on its own as the explosion occurs, a net force acts in the horizontal direction (the normal force from the cannon’s barrel and the weight of the ball cancel one another in the vertical direction. Again, a non-zero net force on the cannon changes its momentum.

When a cannon is fired what happens to the cannonball and the cannon?

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. This is because neither object is moving.

When an object is acted on by many forces it will behave as if it is being acted by a single force which is the vector sum of all the forces acting on it this principle is called?

Two forces with the same magnitude but different directions are not equal forces. The vector sum of all of the forces acting on a body is a single force called the net force . If the net force is equal to zero, the object is said to be in equilibrium.

When all forces acting on an object are balanced?

When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.

When a cannon is fired What is the acceleration?

physics chapter 7 question Flashcards | Quizlet.

When you kick a football you apply a net force to it if a friend kicks it at the same time with an equal and opposite force is there a net force to accelerate the ball?

When you kick a football, your grounded foot provides an outside force to the system, so yes, there can be a net force. If a friend kicks with an equallopposite force, then these forcel each other out, so there can be no net force.

When you hit a baseball with a bat if we call the force of the bat against the ball the action force what is the reaction force?

Consider hitting a baseball with a bat. If we call the force on the bat against the ball the action force, identify the reaction force. The reaction force is the force by the ball on the bat.

Why is the acceleration of a cannon less than a ball?

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.

Did cannonballs ever explode?

Cannonballs were the “standard” shot from the cannons of the 19th century – they had the best range, flew straight and delivered quite a lot of damage to massed infantry and cavalry: There were different kinds. Strictly speaking, cannonballs were solid shot. But there were other kinds too that did explode. OK, let’s start from the beginning.

Do hollow cannonballs have a faster muzzle speed than normal ones?

A hollow, lighter cannonball will have a faster muzzle speed, but will lose it faster, too, due to air resistance. So it depends. And of course the cannonball speed is decreasing all the time. I hope this is of any use.

How big of a cannon did a ship carry?

The size of cannon carried varied dependent on the size of the ship and the larger the cannon the larger the crew needed to haul it’s weight up to the port. A cannon firing 24 pound shot would weigh about two and a half tons.
