they are air and pollution
1). Air resistance 2). Friction in the pivot. These two effects rob energy from the pendulum. Without air resistance or friction in the pivot, a pendulum, once set in motion, would not stop.
The two forces that oppose motion are friction and air resistance. Friction is the force that acts opposite to the direction of motion when two surfaces are in contact, while air resistance is the force that opposes an object's motion through the air.
How does the flow of air reduce friction of the hovercraft in motion?
The two external forces are friction and air resistance. Friction is the force opposing motion when two surfaces are in contact, while air resistance is the force acting in the opposite direction to an object's motion as it moves through the air.
the two things that effect air pressure is force and area
The two forces that affect the motion of a projectile are gravity and air resistance. Gravity acts to pull the object downward, influencing its vertical motion, while air resistance affects the projectile's horizontal motion by slowing it down as it travels through the air.
The two things that cause projectile motion are gravity, which acts vertically, and an initial horizontal velocity. These two factors combined result in the curved path followed by a projectile.
The two forces acting on a projectile in motion are gravity, which always acts downward, and air resistance, which opposes the projectile's motion through the air. Gravity causes the projectile to follow a curved path, while air resistance slows down its movement.
Two forces that resist the forward motion of a bus are air resistance (drag) acting in the opposite direction of movement and friction between the tires and the road surface.
Light and motion are examples of things that have energy. Light carries radiant energy, while motion is a form of kinetic energy.
