Does venus mars or mercury have tidal forces?

Answer 1

Phobos and Deimos are small moons of Mars, and consequently the tidal forces are extremely weak.

Venus and Mercury have no moons, but are still subject to the tidal forces of the sun, and in both cases these forces are considerably larger than they are on Earth (solar tidal forces on the Earth noticeably affect sea levels).

It's also worth noting that tidal forces affect the entire planet (think of a tennis ball being squeezed - in this case the squeezing is caused by the gravitational attraction of the sun).

Answer 2

Mercury does not have any significant tidal forces due to its small size and proximity to the sun. Venus also has minimal tidal forces because of its slow rotation. Mars, being larger and with a longer day-night cycle, experiences slightly more significant tidal forces compared to Mercury and Venus.
