How do you calculate speed when you have the force mass and acceleration?
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.
How do you calculate speed from force?
To calculate speed from force, you would first need to determine the acceleration by dividing the force by the mass of the object. Once you have determined the acceleration, you can use the equation v = u + at, where v is the final speed, u is the initial speed, a is the acceleration, and t is the time taken. By rearranging this equation, you can find the final speed of the object.
How does a pulley change speed?
A pulley changes speed by dividing the distance that needs to be moved by the force applied. When a smaller pulley is used, the speed increases because the force is concentrated over a smaller distance. Conversely, a larger pulley decreases speed by spreading the force over a larger distance.
How do you calculate the force needed to pull a mass of 20gk at a uniform slow speed up a plane inclined at an angle of 30 with the horizontal if the coefficient of kinetic friction is 0.20?
To calculate the force needed to pull the mass up the incline at a constant speed, you would use the formula: Force of gravity pulling the mass down the incline (20 kg * 9.8 m/s^2 * sin(30)) + Force of kinetic friction acting against the motion (0.20 * Normal force) = Force needed to pull the mass up the incline. Calculate the Normal force using the mass and angle, then substitute it into the formula to find the force needed.
Which a force changes the speed of an object?
A force can change the speed of an object by either accelerating or decelerating it. The direction and magnitude of the force will determine how the object's speed changes - an applied force in the direction of motion will accelerate the object, while a force in the opposite direction will decelerate it.
How do you calculate forse on a speed time graph?
If you only have the speed/time graph, you can't calculate force out of it. You could if you also knew the mass of the object that's speeding along, but not with the speed alone.
How do you calculate speed when you have the force mass and acceleration?
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.

How do you calculate HP need to keep constant speed?
It is equal to the retarding force due to friction.
Why can you only calculate a stone's average speed during its fall?
That is just not true! If you can calculate its average speed you should be able to calculate its speed at any point in time during its flight, including its final velocity.
How does a pulley change speed?
A pulley changes speed by dividing the distance that needs to be moved by the force applied. When a smaller pulley is used, the speed increases because the force is concentrated over a smaller distance. Conversely, a larger pulley decreases speed by spreading the force over a larger distance.
Why gravitational force increases when you fly with supersonic speed?
Gravitational force depends only on an object's mass and its distance from the center of the earth. Its speed has no effect on the gravitational force.
How much centripetal force is needed to keep a 0.24 kg ball on a 1.72 m string moving in a circular path with a speed of 3.0 ms?
Calculate the centripetal acceleration, using the formula:acceleration = speed squared / radius Once you have this acceleration, you can use Newton's Second Law to calculate the force.
How do you calculate the force needed to pull a mass of 20gk at a uniform slow speed up a plane inclined at an angle of 30 with the horizontal if the coefficient of kinetic friction is 0.20?

Calculate the Normal force using the mass and angle, then substitute it into the formula to find the force needed.
What is the centripetal force on a 4 kg moving at meter-SEC around a curve with a radius of 4 meters?
First, calculate the centripetal acceleration, as speed squared divided by radius.Then you can use Newton's Second Law to calculate the corresponding force.
Which a force changes the speed of an object?
A force can change the speed of an object by either accelerating or decelerating it. The direction and magnitude of the force will determine how the object's speed changes - an applied force in the direction of motion will accelerate the object, while a force in the opposite direction will decelerate it.
How do i calculate Mechanical friction loss in a conveyor system?
To calculate mechanical friction loss in a conveyor system, you can measure the force needed to move the conveyor belt at a constant speed using a dynamometer. By dividing this force by the weight of the load on the conveyor belt, you can calculate the coefficient of friction. Then, you can use this coefficient in conjunction with the belt length, speed, and other factors to determine the mechanical friction loss.
