What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.
What two things influence the size of a friction force?
The size of a friction force is influenced by the weight of the object and the roughness of the surfaces in contact. A heavier object will exert a greater frictional force, while rougher surfaces create more resistance and increase friction.
Describe the size and direction of the frictional forces when a car stops on a flat road?
When a car stops on a flat road, the frictional force acting on the car is static friction and its direction is opposite to the direction of motion. The magnitude of the static frictional force is equal in magnitude and opposite in direction to the force applied by the car's brakes to bring it to a stop.
What depends on the roughness of the surface and size or weight of the object?
The frictional force between the object and the surface depends on the roughness of the surface - smoother surfaces generally have lower friction. The weight or mass of the object affects the normal force acting on it, which in turn influences the frictional force.
What forms as a result of the wind's frictional force on water?
Waves form as a result of the wind's frictional force on water. The wind transfers its energy to the water, causing it to move and generate waves. The size and shape of the waves depend on the strength of the wind and the distance it travels over the water.
What determines the size of frictional force?
The size of the normal force and coefficient of friction determines the size of frictional force.
What determines the size of a frictional force?
The size of a frictional force is determined by the roughness of the surfaces in contact and the normal force pushing them together. The frictional force opposes the motion of the objects and increases with the weight of the objects in contact.

Name four factors that influence contractile force and two that influence velocity and duration of contraction?
The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
Describe the size and direction of the frictional forces when a car stops on a flat road?
When a car stops on a flat road, the frictional force acting on the car is static friction and its direction is opposite to the direction of motion. The magnitude of the static frictional force is equal in magnitude and opposite in direction to the force applied by the car's brakes to bring it to a stop.
What size force would cause an aircraft of 1200 kg to accelerate up to 6gS?
Impossible to say as you have given no frictional/resistive force.
What depends on the roughness of the surface and size or weight of the object?
The frictional force between the object and the surface depends on the roughness of the surface - smoother surfaces generally have lower friction. The weight or mass of the object affects the normal force acting on it, which in turn influences the frictional force.
What enviormental factors can influence the size of a duck?
no
What factors influence the size of a wave?
wavelength and wind
What forms as a result of the wind's frictional force on water?
Waves form as a result of the wind's frictional force on water. The wind transfers its energy to the water, causing it to move and generate waves. The size and shape of the waves depend on the strength of the wind and the distance it travels over the water.
How big does a goldfish grow and what factors can influence its growth size?
A goldfish can grow up to 12 inches in length, depending on factors like genetics, diet, water quality, and tank size. These factors can influence the growth size of a goldfish.
How big do tetras get and what factors can influence their growth size?
Tetras typically grow to be around 1-2 inches in size. Factors that can influence their growth size include the quality of their diet, water conditions, tank size, and genetics.
