Multiple Choice
Which of the following situations would be true according to Newton's law of reaction?
A) A basketball is in flight (under the affect of gravity) and will continue to travel forward with constant horizontal velocity until stopped by another external force (such as hitting the ground, the hoop or being caught by another player)
B) A soccer player kicks a ball across the field. As the player applies a force to the ball with their foot, the ball applies an equal and opposite force onto the player's foot.
C) A javelin is in flight. Acceleration due to gravity can affect the vertical component of the javelin's flight but not the horizontal component.
D) A volleyball player spikes the ball. The change of motion (momentum) of the ball is proportional to the amount of force applied by the player and inversely proportional to the mass of the ball.
E) A shot-putter uses specific technique to maximise the distance the shot put is thrown. One aspect of this technique involves increasing the amount of time that they apply the force on the shot put so as to increase the impulse.
