How many pushes or pulls can act on an object without causing it to speed up or slow down?
It's not a question of "how many" but of "how strong".
In order for an object to speed up or slow down...
∑F > µY
Where ∑F = the summation of forces (add up all of the forces acting on an object, with opposite directions being opposite signs--ie, left is negative, right is positive for force strength) = "pulls" (+) added to your "pushes" (-)
and
µ = the coefficient of friction = the force retarding the movement of your object
and
Y = the component of the force with which gravity is pulling down on your object that is perpendicular to the plane on which it rests.
IN OTHER WORDS,
On a flat surface, an object will only move if, when you add up all of the "pulls" (positive numbers) with the "pushes" (negative numbers) you reach a number larger than the force of friction acting on the object from just sitting still.
The force of friction is literally just a fraction of the object's weight, in the case of a flat surface (not on an incline.) For that reason, you can put a lot of pushes and a lot of pulls on a really heavy object before it moves.
Additionally, if you push and pull with the same force, regardless the friction on the object, the object will not move, because the forces cancel each other out and friction becomes irrelevant.

When one object pushes or pulls another object the first object does what to the second object?
When one object pushes or pulls another object, the first object exerts a force on the second object, causing it to move or change its state of motion. This force depends on the magnitude and direction of the push or pull applied by the first object.
What are pushes and pulls that may cause motion?
Pushes can be exerted by forces like gravity or a person pushing an object. Pulls can be exerted by forces like tension in a rope or a person pulling an object. Both pushes and pulls can cause motion by applying force to an object in the direction of the motion.
When one object pushes or pulls another object the first object is what a force on the second object?
Pulling
When one object pushes or pulls another object the first objects is what?
When one object pushes or pulls another object, the first object is exerting a force on the second object. This force can cause a change in the motion or shape of the second object, depending on the direction and magnitude of the force applied.
How can pushes and pulls affect an object?
Pushes and pulls can affect an object by changing its motion or position. A push can increase an object's speed or move it in a particular direction, while a pull can slow down or stop the object. The magnitude and direction of the force applied determine how the object responds to the push or pull.

What force tending to make an object move is called?
The force that tends to make an object move is called a driving force or propulsive force. It is the force that pushes or pulls an object in a particular direction, causing it to accelerate or maintain its motion.
What are pushes and pulls?
pushes and pulls are things you do when energy is applied
What pushes up if gravity pushes down?
Gravity pulls "down" and the opposite force is provided by whatever is beneath the object.
What makes non-living things move?
Wind, water, other forces that that pushes or pulls the object.
In science a push or pull is known as?
Forces which also gives off energy to an object are pushes and pulls.
What 2 forces act on a object in water?
Two forces that act on an object in water are buoyant force, which pushes the object upwards, and gravity, which pulls the object downwards.
What is a force that pushes or pulls known as?
A force that pushes or pulls is known as a mechanical force. It is a type of interaction that causes an object to move, change speed, or change direction. Examples of mechanical forces include tension, compression, friction, and gravity.
