Why do lorries need a force to keep them moving at a steady speed?
They need the force to overcome the friction between the lorry and the road.
How is it possible for a car to be accelerating if its speed is a steady 65 mph?
The term accelerating means increasing in speed, so if a car holds its speed steady at 65 mph, it is not accelerating. It is still running its engine, to overcome air resistance and other forms of friction, but that is not the same thing as acceleration.
What uses a cushion of air to reduce friction?
A hovercraft use a cushion of air to reduce friction. In extreme engineering applications there are also air bearings, bearings where a steady flow of air acts as a lubricant between two very finely machined surfaces to keep them apart.
What is another way to reduce friction?
Friction can cause a lot of damage on rough surfaces. Friction also reduces the efficiency of mechanisms and releases heat that can damage parts, so we often want to minimize its effects by reducing the surface areas that are in contact or using a lubricant such as, oil, grease, and graphite.
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.

What is the simile of as steady as?
As steady as a rock

What types of friction are on a roller coaster?
It provides undesired slowing of the coaster on its path but it is essential for the brakes to stop it at the station.
What is the opposite of steady?
it is move for the opposite of steady
Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
What do lubricants do to friction by replacing sliding friction with fluid friction?
Lubricants reduce friction by replacing sliding friction with fluid friction.
Which friction is greater sliding friction or static friction?
Static friction
Which force is weakened when the floor is wet?
Friction is reduced on a wet floor.
