What else can I help you with?
True or false the greater the surface area of an object the greater the air resistance?
True. Air resistance is proportional to surface area, with larger surface areas creating more drag as the object moves through the air. This can result in the object experiencing greater resistance and slowing down.
Would rolling friction reduce the net force of an object to zero?
Only if the object does not MOVE. If it moves in any direction, then the NET Force on the Object is NOT ZERO, it is equal to the (Applied Force) - (Friction Force). So the answer to your question is FALSE.
What would be the effect upon an object if the two forces acting were not lined up?
If the two forces acting on an object are not lined up, the object will experience a net force that is a combination of the two forces. This will result in the object accelerating in a direction that is a combination of the two forces, based on their magnitudes and directions.
What forces act against momentum?
I don't see how anything can "act against momentum"; momentum is always conserved. If there is friction, the movement of the object will be slowed down; but in this case, momentum is transferred to the air, or whatever is slowing down the object in question. Total momentum will be conserved.
Is it true that the 28 hour day organization has found out how to slow down earth?
False
what; forces cause SOME changes in motion true or false?
True. Changes in motion are caused by forces acting on an object, such as gravity, friction, air resistance, and applied forces. These forces can either speed up, slow down, change the direction, or stop the motion of an object.
Is it true or false that an object would accelerate when it is slowing down?
False. An object is slowing down when its speed is decreasing, which means it is decelerating, not accelerating in the direction of motion.
A force will make a moving object slow down or stop true or false?
True. A force acting in the opposite direction to the motion of a moving object will slow it down or stop it. This is known as friction or drag.
A force can make a object slow down or stop true or false?
True. A force can act in the opposite direction of the object's motion, causing it to slow down and eventually stop. This is known as deceleration.
Is it true or false that the motion of an object is affected by friction?
True, friction is a force that opposes the motion of an object when it is in contact with another surface. Friction can cause the object to slow down or stop moving.
Is the following sentence true 'unbalanced forces acting on an object will change the objects velocity'?
Yes, the statement is true. Unbalanced forces acting on an object will cause a change in the object's velocity. This change can involve speeding up, slowing down, or changing direction.
Is it true or false balanced force cause a change in motion?
though different terminology is used. Motion is thought of in acceleration and velocity. Now, velocity is just the distance covered over an amount of time, or speed. Acceleration is the change in speed. In general terms, any object that is standing still is being acted upon by equal and opposite forces, and if one of those forces was changed, then the object would undergo acceleration. Think of a person holding a coffee cup. Gravity is working on the object to pull it down, and his or her arm is pulling equally in the opposite direction to keep it up. If the person were to let go, there wouldn't be the upward force, and the cup would accelerate towards the Earth, and its "motion" would be changed. TRUE!
Is it true or false that friction acts to speed up the motion of an object?
False. Friction acts to oppose the motion of an object, slowing it down. It creates resistance between surfaces in contact, converting some of the kinetic energy into heat.
True or false the greater the surface area of an object the greater the air resistance?
True. Air resistance is proportional to surface area, with larger surface areas creating more drag as the object moves through the air. This can result in the object experiencing greater resistance and slowing down.
A negative slope on the velocity vs time graph indicates that the object is not accelerating true or false?
False. A negative slope on the velocity vs time graph indicates that the object is decelerating or slowing down, but it is still accelerating in the opposite direction.
Why is '' a force can make in object slow down or stop '' true?
This statement is true because a force acting in the opposite direction of an object's motion can cause deceleration, ultimately leading to a decrease in speed and eventually stopping the object if the force is strong enough to overcome its inertia. Examples of forces that can slow down or stop an object include friction, air resistance, and braking forces.
Acceleration will only speed up an object True or false?
False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.
