In physics, what is the fundamental role of a force concerning an object's motion?

To provide the energy an object needs to exist

To cause a change in the object's state of motion

To maintain an object's current speed and direction

To decrease an object's overall mass

An asteroid is moving through the vacuum of deep space, far from any planets or stars. If it is traveling in a straight line at 1,000 km/s, what will its motion be like one hour later?

It will have gradually slowed down and stopped.

It will continue moving in a straight line at 1,000 km/s.

It will have accelerated to a much higher speed on its own.

It will have started to curve in a random direction.

The ball is seeking its natural state of rest.

The ball has run out of its initial energy.

A force, such as friction from the grass, is acting on the ball.

The initial kick was not strong enough to sustain motion indefinitely.

It proves that all motion in the universe will eventually cease.

It allows scientists to ignore objects that are not accelerating.

It establishes a predictable standard; any change from this standard implies a force has acted.

It is primarily used to demonstrate that friction is a universal force that always opposes motion in every situation.

The initial force from the push was completely used up by the car's motion.

The car's natural tendency is to be at rest, so it stops on its own accord.

An opposing force, such as friction, acted on the car to change its motion.

All moving objects require a continuous, uninterrupted force to keep them in motion.
