How do you determine the net force on an object?
Decide which direction is positive motion.
Motion is the opposite direction is negative
The forces must in a straight line!!
Add all the forces in straight line acting on the object.
Example
To the right is positive
A 5 N force pushes a 10 Kg object to the right.
A 2 N force pushes the same 10 Kg object to the left.
The 5 N forces is positive and the 2N force is negative
Net force = +5 N - 2 N = + 3 N
To determine the acceleration use Newton's 2nd law of motion
F = Mass * acceleration
+ 3 N = 10 Kg * a
a = 10 Kg ÷ + 3 N
a = +3 ⅓ m/s^2
The positive sign means the object is accelerating to the right!!
If the forces are not linear, you must use vectors, but the net force in any direction is still the sum of the vectors in that direction.
The speed or velocity of the object before impact and the mass of the object are two important factors that determine the force of impact. The greater the speed or mass of the object, the higher the force of impact will be.
The factors that determine how much an object accelerates when a force is applied to it are the magnitude of the force applied and the mass of the object. The greater the force applied, the greater the acceleration of the object. Conversely, the greater the mass of the object, the smaller the acceleration for a given force.
To determine the g force experienced by an object in motion, you can use the formula: g force acceleration due to gravity x mass of the object. This formula helps calculate the force exerted on an object as it accelerates or decelerates.
The two factors that determine the amount of work done on an object are the force applied to the object and the distance over which the force is applied. Work is calculated as the product of the force and the displacement of the object in the direction of the force.
When an unbalanced force acts on an object, it will cause the object to accelerate in the direction of the force. The greater the force applied, the greater the acceleration of the object. The direction of the force will determine the direction of the object's motion.
To determine the average force acting on an object, you can use the formula for average force, which is calculated by dividing the total force applied to the object by the time over which the force was applied. This formula helps to find the overall force exerted on the object over a period of time.
To determine the net force acting on an object, you need to add up all the individual forces acting on the object in the same direction and subtract any forces acting in the opposite direction. The net force is the overall force that influences the object's motion.
The buoyant force acting on an object is determined by the volume of the object submerged in a fluid and the density of the fluid. This force is equal to the weight of the fluid displaced by the object.
To determine the total force acting on an object, you can use the formula: Total Force Mass x Acceleration. This formula combines the object's mass and the acceleration it experiences to calculate the overall force acting on it.
Force can cause an object to move by exerting a push or pull on the object. When a force is applied to an object, it can overcome the object's inertia and accelerate it in the direction of the force. The magnitude and direction of the force determine the speed and direction of the object's movement.
To determine the friction force when given the mass and acceleration of an object, you can use the formula: friction force mass x acceleration. This formula helps calculate the force resisting the motion of the object due to friction.
To determine the impulse of an object, you can use the formula: Impulse Force x Time. This formula calculates the change in momentum of an object by multiplying the force applied to it by the time the force is applied.
