Why must the mass in F MA include the hanging mass as well as the mass of the cart?

The weight of the hanging mass provides tension in the string, which helps to accelerate the cart along the track. This results in both masses having the same magnitude of acceleration but the direction of the acceleration will be different.

What is the force that pushes you back into your seat when your car accelerates?

Common Explanation: “G Forces,” caused by the acceleration, push you back into your seat.

What is the formula if force?

It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

What is the relationship between acceleration and force in F Ma?

Newton’s second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object’s acceleration.

When calculating the force F acting on each hanging mass It was assumed?

when calculating the force f acting on each hanging mass it was assumed that g = 9.81 m/s^2, though the exact value, in fact, varies from place to place on earth.

What happened to the acceleration of the cart as the weights on the holder increased?

Its velocity and therefore acceleration increases. Adding mass to the cart causes it to take more time to hit the barrier. Its velocity and therefore acceleration have decreased.

How can we relate the first law of motion to a moving car?

Because, according to Newton’s first law, an object in motion will remain in motion unless an unbalanced force acts on it. When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force.

What is it that throws you back in your seat?

The seat is attached to the car, which is accelerating. The seat applies a force to your body (your body applies an equal but opposite force to the seat!) causing you to accelerate along with the car. The “pushed back into the seat” feeling is really the seat pushing forward into your back.

What can you say about the relationship between mass and acceleration when the applied force is constant?

According to Newton’s second law of motion, acceleration is inversely proportional to the mass when the force is a constant. The acceleration is directly proportional to the force when the mass remains constant.

What is the formula for force in physics?

Force Equation F = m a Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

What is the fmax of a block with constant velocity?

Fmax= usN Once the block has been set in motion, the force F needed to keep itin motion with a constant velocity is usually less than the critical forceneeded to get the motion started. In this situation we are dealing withkinetic frictionand the friction force fkis given by

What is force equal to mass times acceleration?

It is a concise statement of Isaac Newton’s Second Law of Motion, holding both the proportions and vectors of the Second Law. It translates as: The net force on an object is equal to the mass of the object multiplied by the acceleration of the object. Or some simply say: Force equals mass times acceleration.

What is the normal force when there is no acceleration?

(Neglect air resistance.) Since there is no vertical acceleration, the normal force equals the gravity force. A rightward force is applied to a 10-kg object to move it across a rough surface at constant velocity. The coefficient of friction between the object and the surface is 0.2.
