What else can I help you with?
Action reaction forces always act on the same objects True or false?
False. Action-reaction forces always act on different objects. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
When the forces acting on an object are unbalanced the net force is zero true or false?
The net force is the vector sum of all the forces acting on a body.
Can earth push an object forward with a reaction force?
Yes, the Earth can push an object forward with a reaction force. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When an object exerts a force on Earth, Earth also exerts an equal force back on the object, causing it to move forward.
True or false the motion of an object thrown at an angle is projectile motion?
True. Projectile motion describes the curved path an object follows when thrown or projected near the Earth's surface, under the influence of gravity, while also moving horizontally.
Is it true or false that balanced forces can change an object's direction?
False. Balanced forces do not change an object's direction. Balanced forces only keep an object at rest or in a uniform motion in a straight line. If an object changes direction, unbalanced forces are acting on it.
Only the earth exerts gravitional force on all object true or false?
False. All objects with mass exert gravitational forces on each other, not just the Earth.
When you push downward on Earth to make a pole vault Earth exerts an equal force on the pole. true or false?
true
Only the earth exerts gravitional force on all object is it true or false?
False. Every object attracts every other object, through the gravitational force.
Is the Earth exerts on the Moon a force acting at a distance?
False,since it's an air resistance and it's a contact force.
When you push downward on earth to make a pole vault earth exerts an equal force on the pole is this true or false statement?
True. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push downward on the Earth to make a pole vault, the Earth exerts an equal force upward on the pole.
True or false The Moon orbits Earth and not the Sun because the Sun doesn't exert a gravitational force on the Moon?
False. The Moon orbits around Earth due to Earth's gravitational pull, but the Sun also exerts a gravitational force on the Moon. The combined gravitational forces of Earth and the Sun control the Moon's orbit.
Does newtons second law state that if an unbalanced force acts on an object it will move at constant velocity?
No, Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma). If there is an unbalanced force acting on an object, it will accelerate, not move at a constant velocity.
Action reaction forces always act on the same objects True or false?
False. Action-reaction forces always act on different objects. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
When the forces acting on an object are unbalanced the net force is zero true or false?
The net force is the vector sum of all the forces acting on a body.
Can earth push an object forward with a reaction force?
Yes, the Earth can push an object forward with a reaction force. This is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When an object exerts a force on Earth, Earth also exerts an equal force back on the object, causing it to move forward.
When you jump on the ground the Earth exerts a greater force back up on you because it is so massive.?
The force that you exert on the Earth is equal to the force that the Earth exerts on you; for every action there is an equal and opposite reaction, so says Newton. What is different is the amount of motion that results. You move, and the Earth (apparently) does not. Actually the Earth is moving all the time, in its orbit around the sun and by rotating on its axis, but it does not noticeably move because you jump on the ground. And that is indeed because it is much more massive than you are. False.
If speed of particle remains constant then it means that no unbalanced force act on it Is it true of false?
true
