What happens when a force of a constant magnitude acts perpendicular to the direction of motion (at all points in time)?

Bonus : Support your answer with an example.

Acceleration remains Constant Momentum remains Constant Kinetic Energy remains Constant Everything remains Constant. The force has no effect. Velocity remains Constant

Conditions mentioned in question leads to circular motion ex. Gravity-moon rotating around earth. Speed is constant in circular motion but velocity, a vector is not constant because direction is continuously changing. Likewise for acceleration or net force.

I wrongly thought that momentum is scalar that I eliminated constant kinetic energy. I thought acceleration as I wrongly thought that parabola is a case but actually not. I should have answered correctly but very unfortunately not.

This is a good question. When I was 19 years old, a colleague asked about circular motion and parabolic motion. Actually, only a circular motion describe the situation of this question. Too tired to answer. I should like to answer correctly.

CIRCULAR MOTION.

If a spacecraft traveling in a straight line in space fires a perpendicular propeller fixed onto the spacecraft for a constant acceleration continuously, then what sort of path that it shall travel following this extra addition of constant force?

When the force acts perpendicularly then the work done on the car is 0.Therefore the car does not gains any kinetic energy(constant).

eg. a stone tied to a thread revolving in a circle. imagine that !
