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 do you need to have to change speed for force acting on?

To change the speed of an object under the influence of a force, you need to apply a net force in the direction of the desired acceleration. This force must overcome any opposing forces affecting the object's motion, such as friction or air resistance. The magnitude and direction of the force applied will determine the resulting change in speed.


What is needed to change the speed of an object?

To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.


What happensto the speed of an object if a unbalanced force acts on it?

Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.


Why does a car need force when its going at a low speed?

Force is any influence that allows an object to undergo change. Force is also Mass x Acceleration, and acceleration is a change in velocity. Therefore, the more force you have, the more positive acceleration you have, and therefore the higher the speed.


How do you calculate force if you only have speed?

To calculate force when given speed, you would need to know the mass of the object. The equation that relates force, speed, and mass is F = m*a, where F is the force, m is the mass, and a is the acceleration (change in speed over time). Without knowing the mass or acceleration, it is not possible to calculate the force.

How does an unbalanced force change speed and direct an object?

An unbalanced force acting on an object can change its speed and direction. If the force is greater than the opposing forces, such as friction or air resistance, the object will accelerate in the direction of the force. The greater the unbalanced force, the greater the change in speed and direction of the object.


When do you use pulley?

1-To force change. 3-to move to change. 4-speed. 5-force 6 We high-speed we at least. 7-force at least.


Can An unbalanced force cause an object to change its speed?

Yes, an unbalanced force can cause an object to change its speed by accelerating or decelerating it. When the net force acting on an object is not zero, it will cause a change in the object's velocity, which includes changes in speed.

Force


A ..is required to change the speed and direction of a moving body?

Force. Change in speed and direction is change in velocity. Change is velocity is called acceleration a=F/m.. The amount of change is the amount of acceleration and that depends inversely on the mass and directly on the force.
