What else can I help you with?
When used a shovel to pry an object the ground acts as a?
When using a shovel to pry an object, the ground acts as a fulcrum, providing a pivot point for leverage. This allows you to apply force to lift or loosen the object.
What kind of force does a porter apply to lift an object?
A porter applies an upward force called the lifting force to lift an object. This force must be larger than the weight of the object to overcome gravity and lift it.
What kind of energy is in a falling object?
Kinetic energy of a falling object can be calculated for a specific height at a specific point since a falling body accelerates which means that it's velocity is changing every moment. To calculate the kinetic energy of a falling body at a certain height, we should know the mass of the body and its velocity at that point.Then we can apply the following formula: K.E. of an object = 1/2(mv2)
How does newton 1st law apply to a falling object?
It doesn't, since the conditions don't apply. The conditions for Newton's First Law are that there is no net force on an object - there must be no force on the object, or the vector sum of the forces must be zero.
Why does an object move when you push agaianst it?
Because you're applying force the object, which unless the ground has glue or something to keep the object in place can't stop it from moving.
What are the examples of balance force?
If the forces on an object are balanced, it won't move. This would apply to a captive balloon, held to the ground by a rope. The upward force of the balloon's buoyancy is balanced by a downward force in the rope, and these must be equal. The same argument for you sitting still in your chair, your weight is balanced by an upward force in the chair.

How can you explore space if gravity attracts objects toward earth?
The same way you walk up a flight of stairs while gravity attracts you toward earth ... you apply an upward force to the object that's greater than the downward force of gravity. When you do that, the net force on the object is upward, and it accelerates away from the earth.
When does inertia apply to a water bottled rocket?
Inertia applies to a water bottle rocket during its launch and flight. When the rocket is initially at rest, it resists any change in motion until the pressurized water is expelled, causing it to accelerate upward. As the rocket ascends, inertia also affects its trajectory; when the thrust decreases and gravity pulls it back down, the rocket continues moving upward momentarily due to its inertia before falling back to the ground. This principle illustrates Newton's first law of motion, where an object in motion stays in motion unless acted upon by an external force.
How does newton 1st law apply to a falling object?
It doesn't, since the conditions don't apply. The conditions for Newton's First Law are that there is no net force on an object - there must be no force on the object, or the vector sum of the forces must be zero.
How to prove that normal force is equal to the product of mass and gravity?
The normal force is what prevents an object from falling through the ground. The force of gravity is equal to the product of the mass and acceleration due to gravity, so the ground that the object sits on must apply an equal force in the opposite direction (Newton's Third Law), other wise the object would fall through.
Why does an object move when you push agaianst it?
Because you're applying force the object, which unless the ground has glue or something to keep the object in place can't stop it from moving.
How do you produce the motion of an object?
Motion of an object can be produced by applying a force to it. According to Newton's laws of motion, an object will remain at rest or in uniform motion unless acted upon by an external force. By applying a force in the direction you want the object to move, you can produce its motion.
How can you change the acceleration of an object?
Apply some force to the object.
If you throw a heavy object forward you tend to fall back. Why?
When you throw a heavy object forward, according to Newton's third law of motion, there is an equal and opposite reaction pushing you backward. This reaction is due to the force that you apply to the heavy object causing an equal reaction force in the opposite direction, leading to you falling back.
