A force of 10 N is applied for 5 s to a 25 kg object at rest on a horizontal frictionless surface The velocity the object would obtain in 5 s is?
The relevant equation of motion for an object initially at rest is:
v = a t
v = velocity, a = acceleration, t = time
Newton's 2nd law tells us that F = ma, where F = force and m = mass. So we can substitute one into the other to get:
v = F t / m = (10 N) (5 s) / (25 kg) = 2 m/s
After 5 seconds, the velocity would be 2 m/s.

What happens to Earth surface when horizontal pressure is applied to rocks?
When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.
Can acceleration happen on a frictionless surface?
yes
When and object slides over a smooth horizontal surface how does the force of friction depend on the force of gravity on the object?
If the surface is smooth then it is almost frictionless. Hence the body will continue to move with constant velocity. However the object continues in a circular path and the weight is thus the centripetal force. It is assumed that the surface is very large)
What is a downward flowing air current?
A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
The amount of horizontal force required to start in motion an object sitting on a horizontal surface must be greater than the force of static friction acting on the object. This is because the force of static friction opposes the applied force until the object starts moving.
What happens when three blocks are placed on a frictionless horizontal surface?
When three blocks are placed on a frictionless horizontal surface, they will remain stationary unless an external force is applied to them. If a force is applied to one of the blocks, it will move in the direction of the force, while the other blocks will remain stationary due to the absence of friction.
What happens when three blocks are placed on a horizontal frictionless surface?
When three blocks are placed on a horizontal frictionless surface, they will remain stationary and not move because there is no force acting on them to cause them to move.
When a horizontal force equal to its weight is applied to an object on a frictionless surface what is its acceleration?
9.8 meters (32.2 feet) per second2 horizontally, provided the exercise is performed on or near the Earth.
What velocity has a parallel to Earth's surface?
horizontal.
Definition of hook pan in physics?
In physics, a hook pan refers to a frictionless horizontal surface attached to a spring scale used for measuring force. This setup allows for the measurement of force applied parallel to the surface with minimal interference from friction.
Will a skateboard go faster if you push it with the same force for a longer time?
Yes. The force is measured as "acceleration" and is meters per second per second (or velocity per second) or the first derivative of velocity. On a frictionless surface in an environment without air resistance, and if the skateboard is a frictionless mechanism, if the skateboard is moving at a constant velocity, that means the acceleration is zero, which means that there is no force being applied to it and it is a body in motion staying in motion.
What is verlocity parallel to the earht's surface called?
Velocity (not verlocity) parallel to the earth's (not earht's) surface is called the horizontal component of the velocity.
When a force moves objects over a rough horizontal surface at a constant velocity the work done against friction must?
When a force moves objects over a rough horizontal surface at a constant velocity, the work done against friction must be equal to the work done by the applied force to maintain the constant velocity. This is because the force of friction opposes the motion of the object, so the work done by the applied force must overcome the work done by friction to keep the object moving at a constant speed.
What will happen if you apply a force on top of a disk kept on a frictionless surface?
The disc will slow down as a result of the friction applied by the force.
What happens to Earth surface when horizontal pressure is applied to rocks?
When a horizontal pressure is applied to rocks, the earth's surface will form lines that are perpendicular to the direction of the pressure. This can be compared to folds in a wrinkled rug lying on a floor.
Can a frictionless surface exert normal force?
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
Can acceleration happen on a frictionless surface?
yes
