What are the effects of this fuel consumption and the need for streamlining if the force from the engine is moving at a constant speed?
Frequent fuel consumption can lead to high costs and environmental impact due to increased emissions. Streamlining reduces drag on the vehicle, improving fuel efficiency. If the force from the engine is moving at a constant speed, streamlining helps maintain that speed more efficiently.
Should acceleration be constant?
Acceleration is not necessarily constant; it can vary based on different factors such as changes in speed or direction. In scenarios where an object experiences a constant force, acceleration can be constant. However, factors like air resistance or changes in force can cause acceleration to change over time.
Driving along a road at a constant velocity of 100km h-1.the forces opposing the motion of the car total 800N. cars mass is 1200kg.what force do you need to maintain constant velocity?
It doesn't matter what the car's mass is, or for that matter, what speed you're talking about.If the total forces opposing its motion are 800 N, then you need to supply 800 N in the directionof motion in order to maintain a constant speed.
How can you accelerate at constant speed?
Acceleration refers to a change in velocity, so accelerating at a constant speed would be a contradiction. If you want to maintain a constant speed, you need to ensure that the net force acting on the object is balanced so that there is no change in velocity. This means that the total external forces acting on the object must cancel out any resistance forces, like friction or air resistance.
A constant forces of ION pushes a 10 kg box of 10 seconds If the was initially at rest what its speed after 10 seconds?
To determine the speed of the box after 10 seconds, we need to use the formula for acceleration: ( a = F / m ), where ( a ) is acceleration, ( F ) is the force, and ( m ) is the mass. Given that the force is constant and the box starts from rest, we can further use the equation for speed ( v = a * t ), where ( t ) is time. Calculate the acceleration using the force and mass, then use that acceleration to calculate the final speed after 10 seconds.
How do you calculate HP need to keep constant speed?
It is equal to the retarding force due to friction.
Why does a car need force from its engine when moving at a constant speed?
If there be no force ie no deceleration then no need to apply any force to compensate such a deceleration. But deceleration is there due to frictional force between the tyre and the road. Hence to compensate this we have apply acceleration. So force is needed OK Physics laws State that an object in motion will remain in motion until acted upon by an outside force. The car moving at a constant speed is being acted upon by wind resistance, gravity, and friction. Therefore force is needed to retain the constant speed
What state do you called an object with a net force of 0?
The object is in constant, uniform motion. It's moving in a straight line, and at a constant speed ... which may be zero but doesn't need to be.
How could you measure frictional force?
For dynamic friction, measure the force required to maintain a constant speed. If you have to pull with 300 N to maintain a constant speed, then friction is pulling back with 300 N. (If the forces were not balanced, there would be an acceleration.) For static friction, see how much force you need to apply before the object starts moving.

How much force does it take to keep an object moving in a straight line at a constant speed?
To keep an object moving in a straight line at a constant speed, you need to apply a force equal to the force of friction or any other resistive forces acting on the object. This force is called the net external force and is equal in magnitude but opposite in direction to the sum of all resistive forces.

What force do you need to change speed?
The most basic equation in physics, which was formulated by Isaac Newton, is force equals mass times acceleration. So the amount of force that you need to change speed depends both on the mass of the object whose speed you are changing, and the amount of the change in speed.
What is the magnitude of force acting on a body moving with constant velocity?
Certainly not. An object has momentum on account of its motion, which depends on its mass and its velocity. Force may be involved in the object's motion, but doesn't need to be. If we let the discussion become somewhat flabby, we can imagine a constant force applied to an object, and asked what happens to the object's momentum. An object with a constant force acting on it exhibits constant acceleration in the direction of the force. In that situation, the object's speed, and therefore its momentum, are proportional to the time the force continues to act on it.
