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.

Do you think you need a lot of force to change an object's inertia?
That is a tricky question. Possibly you would change an object's inertia if you supplied sufficient force to accelerate it to the speed of light?
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.
What is an force that can cause an object to change its speed and direction.?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
What is the effect of a constant force on speed?
A force, applied to an object, will cause an acceleration, that is, a change in velocity. This may be an increase or a decrease in speed, or a change of direction.
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.
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.

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.

What is needed to change its speed or direction?
Force
What force is acting when you change speed?
Gravvity

What is related to force?
mass, acceleration, motion - speed and velocity, newtons 1st law force = mass * acceleration speed requires force to change force acts on velocity to change it newtons 1st law describes force
What must happen for an object to stop start change speed or change direction?
A net force must be applied to the object. That is, the vector sum of ALL the forces acting on the object must not be zero.
What is change in the speed of an object?
A change in the velocity is produced by a force acting on the object. A change in velocity means a change in speed or direction (or both).
