What is the net force on a car moving in a straight line which a constant speed?
The net force on a car moving at a constant speed in a straight line is zero. This is because the forces acting on the car, such as friction and air resistance, are balanced by the force produced by the engine to maintain the constant speed.
A car is driving at constant speed...... explain why the car will eventually reach a new higher constant speed?
The car will eventually reach a new higher constant speed when it travels downhill due to the force of gravity pulling it downward, causing an increase in its kinetic energy. Once the car reaches this new constant speed, the forces acting on it, such as air resistance and friction, will balance out to maintain the new higher speed.
Why forces acting on a car as it moves along a level highway in still air at a constant speed?
The main forces acting on a car moving at a constant speed on a level highway in still air are the driving force from the engine propelling the car forward and the opposing forces such as friction between the tires and the road and air resistance. When these forces are balanced, the car will continue to move at a constant speed.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.
Infer whether balanced forces must be acting on a car moving at a constant speed?
Yes, if a car is moving at a constant speed, balanced forces must be acting on it. This means that the force pushing the car forward is equal to the resistive forces acting against it (like friction and air resistance), resulting in zero net force and a constant velocity.
What is the net force on a car moving in a straight line which a constant speed?
The net force on a car moving at a constant speed in a straight line is zero. This is because the forces acting on the car, such as friction and air resistance, are balanced by the force produced by the engine to maintain the constant speed.

A race car is traveling at constant speed around a circular track what has to happen to the static friction in order to stay on the track when the speed is doubled?
In that case, the centripetal acceleration - and therefore also the static friction - will increase by a factor of 4.
Infer whether balanced forces must be acting on a car moving at a constant speed?
Yes, if a car is moving at a constant speed, balanced forces must be acting on it. This means that the force pushing the car forward is equal to the resistive forces acting against it (like friction and air resistance), resulting in zero net force and a constant velocity.
Does a car accelerate rounding a curve at a constant speed?
No, a car does not accelerate when rounding a curve at a constant speed. Acceleration occurs when there is a change in speed or direction. In this case, the car is moving at a constant speed but is changing direction, not accelerating.
When does a car move at a constant speed?
A car moves at a constant speed when the acceleration is zero. This means that neither the speed nor the direction of the car is changing. Once all external forces are balanced and there is no net force acting on the car, it will continue to move at a constant speed.
What is the acceleration of a car that travels in a straight line at a constant speed of 135 kilometers per hour?
If a car travels in a straight line with a constant speed, then the car has a constant velocity (determined by direction and speed), and the acceleration is 0.
Are the forces on a car that is traveling at a steady speed balanced or unbalanced?
The forces on a car traveling at a steady speed are balanced. The driving force from the engine is balanced by the resistive forces such as friction and air resistance. This balance allows the car to maintain a constant speed.
What is the acceleration of car that travels in a straight line at constant speed?
Straight line at a constant speed = no acceleration
Does friction increase as speed decrease?
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
