When a person is running and accelerating, the main forces acting on them are the force of gravity pulling them down towards the ground and the force of their muscles pushing them forward to propel them in the desired direction. Additionally, air resistance may also act as a force opposing their motion.
When running downhill, the main forces acting on a person are gravity, which propels the person downward, and air resistance, which opposes the person's forward motion. The person's muscles contract to control their speed and maintain balance.
That's a true statement ... but not in the way you think. "Accelerating" is NOT necessarily the same thing as "speeding up".
When a person sits in a chair, the main forces acting on them are the gravitational force pulling them downward towards the Earth and the normal force exerted by the chair pushing them upward to counteract gravity. Frictional forces between the person and the chair also play a role in keeping them seated comfortably.
No. An object is accelerating if it is changing speed or direction of travel. Since the person in question is running at a constant speed in a straight line, they are not accelerating.
When a book is pushed across a table, there are two forces acting on it: the force applied by the person pushing the book (force of push) and the force of friction acting in the opposite direction on the book due to contact with the table surface.

When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.

Please someone answer!!!!!
When a person lets go of a hammer, it falls due to the force of gravity acting on it. Gravity pulls objects toward the center of the Earth, resulting in the hammer accelerating downward. If no other forces act on it, such as air resistance, it will continue to fall until it hits the ground. This phenomenon is explained by Newton's laws of motion.

Yes, there are several forces acting on the pen. The main forces are gravity pulling the pen downward, the normal force from the surface pushing the pen upward, and the force exerted by a person's hand when holding the pen. These forces can be represented by arrows pointing in their respective directions.
Even though the person is moving at a constant speed, they are changing direction constantly as they go around the track. Since acceleration is defined as any change in velocity, and velocity includes both speed and direction, the person running on a circular track is experiencing acceleration.
The net force on the leash is the vector sum of all forces acting on it. This would include forces such as tension from the person holding it and the weight of the object at the end of the leash. The net force is calculated as the difference between these forces.
