What else can I help you with?
A 5.0kg box is pushed across the floor with a force of 32N What is the frictional force on the box if the boxs acceleration is 3.6mS2?
Frictional force equals 14 Newtons Fnet = Fp - Ff so rewriting the equation gives us: Ff = Fp - Fnet (Fnet is net force, Fp is force of push, and Ff is frictional force) We already know that Fp is 32 N and we can find Fnet by using Newton's Second Law: F = ma Fnet equals 5 kg times 3.6 m/s2 = 18 N So Ff = 32 N - 18 N which equals 14 N
Can the impulse of force be zero even the force is not zero?
Yes, it is possible for the impulse of force to be zero even if the force is not zero. This can happen if the force is applied for such a short period of time that the area under the force-time graph, which represents impulse, is zero.
What force will give a mass of 1 gram?
Mass is not dependent on the forces applied to it. Weight is the force that a mass exerts due to the acceleration of gravity.
If a block and tackle is a simple machine What mechanical advantage does it give the user and what does the user have to give up in exchange?
A block and tackle provides a mechanical advantage by trading distance for force. The user needs to exert less force to lift a heavier load, but they have to pull the rope a greater distance to accomplish the task.
How can a fixed pulley make work easier?
A fixed pulley changes the direction of force applied, allowing the force needed to lift an object to be distributed more evenly. This can make work easier by requiring less effort from the person lifting the object.

What does a force applied to a stationary object give the object?
A force applied to a stationary object can give the object acceleration, causing it to move.
What is the force applied over a period of time that is required to give a stationary object momentum called?
The force applied over a period of time to give a stationary object momentum is called impulse. Impulse is equal to the change in momentum of the object and can be calculated by multiplying the force applied by the time over which it is applied.
What does the force applied to a stationary object give to the object?
"Motion" or "Momentum"
What does a force applied to stationary object give the object?
motion or momentum Motion for A+
Share situations from your work place where the expression has or has not applied Does your organization or any other that you are familiar with give weightage to the expression while arriving at va?
Share situations from your work place where the expression has or has not applied. Does your organisation or any other that you are familiar with, give weightage to the expression while arriving at various decisions? Illustrate your views.
Give example of of an object that is experiencing an unbalanced force?
A book sliding off a table is an example of an object experiencing an unbalanced force. The force of gravity pulling the book downward is greater than the frictional force between the book and the table, causing it to accelerate in the direction of the force.
Can you give me 3 situations where muscular force is manifested?
Lifting a weight, jumping over an obstacle, rowing a boat
What is the force applied over a period of time that is required to give a stationary Objects momentum called?
impulse
How to find the magnitude of impulse in a given scenario?
To find the magnitude of impulse in a given scenario, you can multiply the force applied to an object by the time period over which the force is applied. This will give you the change in momentum of the object, which is equal to the impulse. The magnitude of impulse is a measure of how much the object's momentum changes due to the force applied to it.
What effect force can have on the motion of an object .Give an example of each effect that you write?
Force can change the speed, direction, or shape of an object's motion. For example, a force applied in the direction of motion can increase the speed of a moving car. A force applied perpendicularly to the motion can change the direction of the car without changing its speed. Finally, a force applied to deformable objects, like squishing a ball, can change their shape.
What is the formula to find the mass when they give you the acceleration and mass?
You ignore the acceleration, and just give them the mass. Now, if they give you the acceleration and the applied force, you could use m = F/a.
