When the cart is moving at a constant speed along the track what is the net force on the cart?

When the cart is moving at a constant speed along the track what is the net force on the cart?

Because the speed is constant, the acceleration is zero. Because acceleration is zero, the net force is zero.

What force between the wheel and the track would slow it down?

Only when (hopefully static) friction is present can we slow the car. Kinetic friction is also capable of slowing the car, but we don’t want that because we don’t want to skid the tires. The only portion of the car that touches the road is the wheels/tires. That is the only part where friction can develop.

What is the formula for force and motion?

Newton’s second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.

When the net force on an object moving at a constant velocity is?

According to Newton’s first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero.

What force keeps the car moving around the track towards the center of the track?

Figure 6.12 This car on level ground is moving away and turning to the left. The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road. A minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway.

What other force acts on the car as it moves along the track?

For a race car speeding down a curve, friction acts like the centripetal force, keeping it on its path. For the particle, the magnetic field’s force that acts like the centripetal force when it moves in a circular motion.

What do you call the force on the track that can slow down the car?

In that case, the only source of friction is between the wheels and the road. Friction can be thought of as a force that acts against the direction of an object’s motion, so friction is the outside force that stops the car, according to Newton’s First Law.

What does 1 newton equal?

A newton (N) is the international unit of measure for force. One newton is equal to 1 kilogram meter per second squared. In plain English, 1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.

What is the SI unit of newton?

The SI unit recognized for the measurement of force is Newton. SI Unit of force (F) = (Kg).(m/s2) = (Kg m/s2) This SI unit is termed ‘Newton’ (Kg m/s2).

What is equal to velocity?

The velocity is the time rate of change of displacement. If ‘S’ is the displacement of an object in some time ‘T’, then the velocity is equal to, v = S/T. The units of velocity are m/s or km/hr.

Which ball has more inertia?

The greater an object’s mass, the more inertia it has. So, a bowling ball has more inertia than a baseball.

What does Newton’s first law state?

1. Newton’s First Law of Motion (Inertia) An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

What is another name for Newton’s first law of motion?

Newton’s first law is often called the law of inertia. As we know from experience, some objects have more inertia than others. It is obviously more difficult to change the motion of a large boulder than that of a basketball, for example.

What is the net force of a moving car?

Net force of car = applied force by engine – friction force , to make car move with constant velocity(uniform motion) , acceleration of car should be zero. or net force on car = m*a = m*0 =0 . so to make net force zero, applied force by engine = friction force. that way car can move uniform motion.

What happens to the net force when the object is moving at a constant acceleration?

Explanation: If an object is moving with constant velocity, then its acceleration must be zero. We can then look at Newton’s second law. If the acceleration is zero, then the net force must also be zero.

In what direction is the net force on a car driving at a constant speed around a banked curve?

When a car goes around a curve, there must be a net force toward the center of the circle of which the curve is an arc. If the road is flat, that force is supplied by friction.
