Why does a person move forward when he or she pushes on the sidewalk?
The person's feet push backward on the sidewalk; the sidewalk pushes forward on the person.
Which explanation describes the forces involved for a person to walk down the sidewalk?
The person's feet push backward on the sidewalk; the sidewalk pushes forward on the person.
How does firing gas from a rocket backward accelerate the rocket forward?
Well, according to Newton's third law of motion, for every action there is an equal and opposite reaction, so when the gas pushes against the ground, the ground "pushes" back, forcing the rocket upwards.
Suppose that you fall on a sidewalk while rollerblading Do you exert a force on the sidewalk Does the sidewalk exert a force on you Which of these forces may injure you?
Both, you exert a force onto the sidewalk, and the sidewalk "pushes back" with an equal, but opposite force.
When you walk along the sidewalk you push the earth and the earth pushes you How come no one notices that you pushed the earth?
When you push off, you accelerate away from the earth, and the earth accelerates away from you, but because of the earths great mass the acceleration and distance travelled are incredibly small and cant be discerned.
How does man walk?
When we walk on the ground our foot pushes the ground backward, and in return, the ground pushes our foot forward. The forward reaction exerted by the ground pushes our foot forward. The forward reaction exerted by the ground on our foot makes us walk forward.
Example of 3 laws of motion?
when we walk on the ground, our feet pushes the ground in backward direction, as a reaction ground pushes us in forward direction hence we can walk on the ground.
What is an example of newton third law?
-- When you push on a brick wall with a force of 50 pounds, the brick wall pushes back on you with a force of 50 pounds. That way, the forces on the palm of your hand are balanced, and your hand doesn't accelerate. -- When you stand on the ground with a force of 185 pounds, the ground pushes back on the bottom of your shoes with a force of 185 pounds. That way, the forces on the soles of your shoes are balanced, and your feet don't accelerate.
John pushes his bike along the sidewalk at a constant speed if he increase the force on the bike what happens?
The bike accelerates
If a 70-kg swimmer pushes off a pool wall with the force of 250N at which rate will the swimmer accelerate from the wall?
56
What force pulls liquids to the ground?
Gravity is actually a pushing factor and it pushes liquids to the ground.
Why is it hard to run on ice?
you can walk on the ground because of Newton's third law! One foot exerts a force on the ground in a backward direction (try walking away from a skateboard...) and the reaction force from the ground on you is what pushes you forward. On ice there is much less friction to be able to push backward, hence there will be much less reaction force pushing you forward. That's the physics of it, Newton's third law!
