When you apply force at an angle to the direction of movement, two components result; F.D + FxD. F.D = -FDcos(angle) called work and FXD = FDsin(angle) called torque.
False a force at any angle to the direction of motion can not perform work. Power is the rate at which a force is applied.
In general, force and velocity do not have to be in the same direction; they can be at any angle.
what is the work done if we apply a 1.2N force and we move 4 m in the direction of force
Newton's 1st law of motion: an object will continue on its course at the same speed and direction, if the net force acting on the object is zero. Hence, if you don't apply any net force on the object, its direction and speed will not change (it will not move on a curved path). If you want the object to change direction, you need to apply a net force away from the direction of travel (the net force is pointing at a non-zero angle with the direction of travel).

Just one. Apply a force in the opposite direction of it's movement.

'Acceleration' in that direction results.

As you walk down the stairs, you apply a force to keep yourself from falling down the stairs. The force is in the upward direction, but your movement is in the downward direction. If the force is in the opposite direction of motion, work done by the force is negative. Gravitational force, because it pulls down, does positive work.

If the speed is constant the frictional force must be equal to the propelling force (which is gravity in this case) as any imbalance of forces creates an acceleration. If the 60N is in the same direction as the movement, then the frictional force is also 60N. If 60N is the gravitational force, you'll have to use the angle to calculate the propelling force that acts in the direction of movement. Again, the frictional force will be exactly the same as the propelling force in the direction of movement (only in magnitude, though - the direction of the frictional force (the vector) will be in the opposite direction).
I'm pretty sure it means the motion or movement that is going to happen. So, if you apply force in a direction to a box, the impending motion will be sliding or tipping in the direction of force depending on certain coefficients of friction.
