F=ma, according to Newton's laws, so some more force will accelerate the object (that is, change its velocity in the direction of the force) at a rate of F/m.
Speed is just how fast the object is going, while velocity is a combination of speed and direction. If the force is applied in a direction opposite the velocity, the speed will decrease. If the force is applied in the same direction, it will increase.

What is the Forces of attraction between objects?
Gravitational force.
Why does gravity affect speed?
Because the effect of gravity is to cause forces between every two objects that have mass, and force on an object generally affects its speed.
What changes a objects speed and motion and direction?
A force.
Does speed affect the friction between a road and a skidding tire?
Speed does not affect the force of friction.
What forces can affect an objects velocity but not the speed?
Centripetal forces can.
How does gravitational force affect acceleration?
The force of gravity causes objects to accelerate (speed up) when they fall. This is because of newtons law F=MA force equals mass times acceleration, meaning when you put a force such as gravity on a mass it will accelerate the mass
How does changing the angle of a catapult affect the objects speed?
It shouldn't affect the speed much, but at different angles (and the same speed), an object can reach different distances.
What type of force CAN a change in an objects direction speed or both?
gravitey
Objects moving at a constant speed in a straight are said to be in?
Objects moving at constant speed in a straight line are said to be in equilibrium. That is there is no force acting on them. If a force was acting there would be aceleration and the velocity would change.
How can using more force change an objects speed?
because force=speedxmass, and the other way around.
How the force of air resistant depends on an objects speed?
In general the resistance increases by the 4th power of the speed.
How does a knife decrease the force or the distance?
Because the size of the objects determine the speed and force of the object, the smaller the object, the higher the speed and the less force is applied whereas a larger object will apply more force and less speed.
