true, are you doing the worksheet mr.e gave?
True
When a person lifts a bucket upward, the person exerts an upward force on the bucket, and the bucket exerts a downward force on the person. When a bucket is pushed along the ground, the person exerts a forward force on the bucket, and the bucket exerts an equal and opposite backward force on the person.
When you sit in a chair, your weight exerts a downward force on the chair, while the chair exerts an equal and opposite upward force on you. This is an example of Newton's third law of motion in action.
The air is always pushing down on you, just slightly more under high pressure. You don't notice it because we've evolved to counter this downward force with an outward force of our own.
The most common example is that you throw a ball at the wall, it comes back to you. You do the action and then wall does the reaction by returning the ball with equal magnitude but in a direction opposite to your action.
The same reason bricks exert downward pressure. Gravity.
The same reason bricks exert downward pressure. Gravity.
Gravity exerts a downward force on materials on a slope, causing them to slide or roll downhill. The steeper the slope, the greater the force of gravity pulling the materials downward. This can lead to erosion, landslides, or other slope instability.
gravity at a downward force of 9.8m/s

Earth exerts a downward (towards the ground or Earth) force on your body. At the same time, your body exerts an upward (towards your body) force on the Earth. Your body is the one that seems to move, however, because the mass of your body is so much less than the mass of the Earth.
Sinking air exerts a downward force to form high-pressure systems. As the air sinks, it compresses and warms, leading to the suppression of cloud formation and clear skies. This descending motion creates a stable atmospheric environment and inhibits the formation of precipitation.
A backpack exerts a downward force on the body due to gravity pulling it downward. Additionally, the straps of the backpack exert a force on the shoulders and back to support the weight of the backpack.
True. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push downward on the Earth to make a pole vault, the Earth exerts an equal force upward on the pole.
You can put it on a scale. There's usually one available somewhere near the apples in any produce market, for that exact purpose. The downward force exerted by the apple is referred to as the apple's "weight". It's the magnitude of the gravitational attraction between the mass of the earth and the mass of the apple.
A ball thrown straight will curve downward due to the pull of gravity acting on it. As the ball moves forward, gravity exerts a downward force on it, causing it to follow a curved path towards the ground. This downward curve is influenced by factors such as air resistance and the initial velocity and angle at which the ball was thrown.
