A。When playing football, the force of foot to foot and the force of football to foot are a pair of balance forces
Analysis: A. when kicking a ball, the foot exerts force on Force when playing footballthe ball. The force between objects is mutual, and the ball also exerts force on the foot; B. After the ball is kicked out, it will continue to fly in the air due to inertia, and will be affected by gravity and air resistance; C. Foot to ball force the object under force is the ball, and the direction isForce when playing football forwardThe force used to play football is about
The size, direction and action point of force are called the three elements of force. They can influence the effect of force. When one of the elements changes, the effect of force often changes. In football matcheForce when playing footballs, players often kick "banana ball" and "straight ball", which is the route change of ball movement. If the size of force changesWhen playing football, what force does the ball receive after it is kicked out
(2) After the football is kicked out, in addition to air resistance, it is also affected by gravity in the air. The direction of gravity is vertical downward, and the ball will fall downward; (3) The football will stop after rolling for some distance on the grass, and the movement state has changedThe support and friction of playing football
So a is correct; In the vertical direction, there is no pressure due to the vertical downward gravity and the vertical upward support of the ground, so B is wrong; The football has been kicked out and is not affected by the force of the foot on the ball, so C is wrong; Inertia is a property of the object itself, not a force. D is wrong. So choose a
When playing football, what is the gravitational force on the ball and what is a pair of forces and reactions
The gravity of the ball and the supporting force of the grass on the ball are equal in size, opposite in direction, acting on the same object and on the same straight line. They are a pair of equilibrium forcesWhat is the force of a player playing football
Analysis of test questions: force is the interaction between objects, and force cannot exist separately from the object applying force and the object receiving force; The interaction of forces between objects is mutual. When an object exerts a force on other objects, the object itself will also be affected by the forceThe force of playing football is mutual
People are the objects of study. People are stressed and football exerts force; On the contrary, taking football as the research object, the ball is under force
When playing football, Force when playing footballthe force of the foot changes the direction of the football team, right
This sentence is wrong. When kicking a ball, it is the power work of kicking a ball with feet. It is used for football, which increases the types of forces on football. If the direction of the force is opposite to the direction of football, it will change the direction of football; If the direction of the force is the same as that of the football movement, the speed of the football movement will be increasedWhen kicking a ball, what is the force on the ball? At this time, what is also affected by the force of the ball
All the forces on the ball are forehead. Downward gravity is when he flies. If he is straight away, she is directed to one. The forward inertia is also a downward one. Gravity also has a frictional force
