Inertia - A force is required to change the state of motion.
1 of 9
What is Newtons second law of motion?
Acceleration - The magnitude and direction of the force determines the magnitude and direction of the acceleration.
2 of 9
What is Newtons third law of motion?
Every action has an equal and opposite reaction.
3 of 9
What is linear motion?
Motion in a straight or curved line, with all body parts moving the same distance at the same speed in the same direction.
4 of 9
What is inertia?
The resistance an object has to change in its state of motion.
5 of 9
What is ground reaction force?
The equal and opposite force exerted on a performer who applies a muscular force on the ground.

What is an application of newtons first law?
In a penalty, the ball will remain on the spot (state of rest) unless it is kicked by the player (an external force is exerted upon it)

What is an application of newtons second law?
When a player kicks the ball during the game, the acceleration of the ball is proportional to the size of the force. So, the harder the ball is kicked, the further and faster it will go in the direction in which the force has been applied.

What is an application of newtons third law of motion?
When a footballer jumps up to win a header, a force is exerted on the ground in order to gain height. At the same time, the ground exerts an upward force upon the player.
