Is a cannonball fired balanced?

Is a cannonball fired balanced?

A cannonball fired parallel to the ground: Are forces balanced or unbalanced? When the skydiver is falling, the forces are unbalanced. When the parachute is open, the forces are balanced.

Is a skydiver accelerating downward balanced or unbalanced?

The skydiver accelerates towards the ground. As the skydiver gains speed, their weight stays the same but the air resistance increases. There is still a resultant force acting downwards, but this gradually decreases. Eventually, the skydiver’s weight is balanced by the air resistance.

Which of the following factors affects how easily a moving object can be stopped *?

both (a) and (b)- the object’s mass and speed affect how easily a moving object can be stopped. A rock and an apple that is lighter than the rock are dropped from the same height at the same time.

Are forces balanced or unbalanced?

When the motion of an object changes, the forces are unbalanced. Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force.

What are 3 examples of balanced forces?

Here are some examples of situations involving balanced forces.

• Hanging objects. The forces on this hanging crate are equal in size but act in opposite directions.
• Floating in water. Objects float in water when their weight is balanced by the upthrust from the water.
• Standing on the ground.

What are 3 examples of unbalanced forces?

Examples of unbalanced forces

• Kicking a soccer ball.
• The up and down movement in a seesaw.
• The taking-off of a Rocket.
• Skiing along the mountain slopes.
• Hitting a baseball.
• A turning vehicle.
• Drowning of an object.
• Apple falling on the ground.

Which is the best example of an unbalanced force?

If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

What is an example of an unbalanced force?

If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.

Is constant speed a balanced force?

When we push or pull an object we can make it move. If we push the car we make it move because our push is greater than the other forces acting upon it. If, on the other hand, an object is moving at a constant speed in a straight line then again the forces are said to be balanced.

Is an apple hanging on a tree a balanced force?

For example, when an apple hangs from a tree, the weight of the apple is balanced by the force exerted by the branch on the apple. When an object is moving with changing speed, the net force on it is unbalanced.

Why is rolling a ball down a hill considered an unbalanced force?

Answer: An unbalanced force refers to the force that causes change in velocity that is causes acceleration of the body. An unbalanced force makes a body to change either its speed or direction or both. A ball rolling down a hill, accelerates downwards because of gravitational force.

What is the greatest force at work on Earth?

The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

Who is the strongest force user?

What is the weakest force in the universe?

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.

What is the hardest thing to understand?
