The dry sidewalk has more friction compared to the ice on the icy sidewalk
Four contact forces are normal force (force exerted perpendicular to the surface), frictional force (force opposing motion), tension force (force in a stretched object), and applied force (force applied to an object by a person or another object).
A spring scale can be used to measure the force or weight exerted on it. This can include measuring the weight of objects, the force required to stretch or compress a spring, or the force exerted by a person pulling or pushing on the scale.
Friction is the force that stops boots from slipping. The rough surface of the sole of the boot interacts with the ground, creating resistance to sliding. Additionally, the weight of the person wearing the boots helps to increase the frictional force and prevent slipping.
A landslide was likely the natural force that caused the hill to flow into the town. Heavy rainfall, earthquakes, or volcanic activity can trigger landslides and result in the movement of large amounts of soil and rock downhill.
Blood Mountain was formed by a combination of constructive and destructive forces. The mountain likely started forming through tectonic activity, which is a constructive force, while erosion and weathering played a role in shaping its final features, which are destructive forces.
Friction
The dry sidewalk has more friction compared to the ice on the icy sidewalk
When a person pushes against the sidewalk, they exert a force in the opposite direction. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means the sidewalk exerts an equal and opposite force on the person, propelling them forward.
The force of friction between the person's shoes and the sidewalk prevents their feet from slipping. Friction is generated by the contact between the irregularities on the shoe sole and the rough texture of the sidewalk surface, providing the necessary grip for walking.
Frictional force. On a rainy day, the property of the sidewalk changes the coefficient of friction, causing you more likely to fall.
Both, you exert a force onto the sidewalk, and the sidewalk "pushes back" with an equal, but opposite force.
When a person walks down the sidewalk, the main forces involved are gravity pulling the person downward towards the ground, and friction between the person's feet and the sidewalk providing the necessary grip to propel the person forward. Additionally, there is the force of the person's muscles contracting to move their legs and body in a coordinated manner.
The force of a skateboard rolling down the sidewalk is primarily due to the push-off force provided by the skater's foot. Additionally, factors such as gravity, friction between the wheels and the sidewalk, and air resistance also contribute to the overall force propelling the skateboard forward.
friction
Friction is the force that keeps you from sliding on an icy sidewalk. When you walk, the friction between the soles of your shoes and the ice surface prevents you from slipping.
The person will likely live, unless the force was extreme.
When the skateboarder pushes on the ground with her foot, she exerts a force on the ground in one direction, causing the ground to exert an equal and opposite reaction force on her in the opposite direction. This reaction force propels the skateboard and the skateboarder forward, resulting in acceleration down the sidewalk.
