Yes. If you ram your car into a wall, you are using both force and speed to achieve that goal.

A falling object that has reached its terminal speed continues to gain what?
neither speed nor acceleration
How can wheel and axle be used to gain force?
NO
What is effect of the weight of the helicopter on the terminal speed?
When an object falls in the air, the air resistance opposing its motion increases as its speed rises, so reducing its acceleration. Eventually air resistance acting upwards equals the weight of the object acting downwards. The resultant force on the object is then zero since the two opposing forces balance. The object falls at a constant velocity, called its terminal velocity, whose value depends on the size, shape and weight of the object. This is just like Newton's laws, an object will accelerate if the forces acting upon it are unbalanced; and further, the amount of acceleration is directly proportional to the amount of net force (unbalanced force) acting upon it. Falling objects initially accelerate (gain speed) because there is no force big enough to balance the downward force of gravity. Yet as an object gains speed, it encounters an increasing amount of upward air resistance force. In fact, objects will continue to accelerate (gain speed). Or summat like that...
What makes a garlic press a simple machine?
A garlic press uses a lever and has its fulcrum at one end of the lever arm. The load (garlic) is between the fulcrum and the effort. When using a simple machine like the garlic press we gain a mechanical advantage by increasing the amount of force we wish to use.
What force causes a falling object to gain kinetic energy?
gravity
How is a lever different from a machine made with ropes and pulleys?
Both pulleys and levers are mechanical devices designed to gain an advantage over an inert load force and both are simple machines. The main difference with a pulley system is the direction of force, and the effect can be different.
What is machines mechanical advantage?
it is d ratio of the load to the effort applied to move the load if mechanical advantage>1(ie L/E >1), the machine acts as a force multiplier otherwise as a machine to gain speed mechanical advantage is abbreviated as M.A.
About the new time machine concept?
the new concept of time machine had be ready but i am waiting for the practical work to it .It needs 5,34,567knots of speed waves it can be gain from the only astriods which fall on earth gravitational force it can prooved from the moving particle lawI AM WAITING FOR THAT TIMEBYR.ISMAILSALEM TAMIL NADUINDIA
A falling object that has reached its terminal speed continues to gain what?
neither speed nor acceleration
What type of simple machine is a slingshot?
Is a trampoline a pulley system
How does speed travel through solids?
When the force is done to one side of solid, it will translate the force to the whole entities of the solid piece and each of the small entities gain speed from result of the force pushing it.
Why does a egg gain speed on the way down?
Any falling object, or object that rolls downwards, can gain speed. This can easily be explained by Newton's Third Law: acceleration = force / mass. Force refers to the net force. So, as long as there is a net force downward, the object will continue accelerating. Only when the upwards forces (basically, friction) become as strong as the downward force of gravity will the object start accelerating. In that case, the object is said to have achieved "terminal velocity".
How does a gear make work easier?
it can be used to gain speed or to gain in torque1. if big gear rotates small one then gain in speed2. if small one rotates big then gain in torque3.if both are equal then can be used for either of them
How fast is an object going if its speed and time graph is horizontal?
An object can only gain speed if there is a net force on it. If a net horizontal force acting on an object is large enough, or acts for a long enough time, the object can aquire a speed up to just under the speed of light, 3 x 10^8 m/s.
How does the size of the gears in a gear train affect speed and force?
If the driving wheel has more number of teeth, and the driven wheel has less number of teeth then there will be a gain in SPEED .If the number of tooth in the driver is less in the driving wheel and there is more number of tooth in the driven wheel , there will be a gain in TORQUE.
How do an jet stream gain speed?
why do you think airplanes traveling in the jet stream gain speed going from west to east but lose speed from east to west
Does an object on free fall increase in distance proportional?
an object free falling would continue to gain speed until met by a balanced force i.e. the ground
