Questions and Answers
What accounts for the golfer's greater acceleration compared to the shot-putter?
What accounts for the golfer's greater acceleration compared to the shot-putter?
- The golfer has less mass, resulting in a greater change in motion. (correct)
- Both pushed with different angles.
- The golfer pushed harder than the shot-putter.
- The shot-putter has less mass than the golfer.
According to Newton’s First Law of Motion, what happens to the golfer and shot-putter after they lose contact?
According to Newton’s First Law of Motion, what happens to the golfer and shot-putter after they lose contact?
- They move in a straight line at a constant velocity. (correct)
- They begin to rotate in place.
- They eventually stop due to air resistance.
- They accelerate continuously until hitting an obstacle.
What role does friction play in the motion of the golfer and shot-putter on the ice rink?
What role does friction play in the motion of the golfer and shot-putter on the ice rink?
- There is no friction, allowing for uninterrupted motion. (correct)
- Friction only affects the shot-putter.
- It helps them maintain their direction.
- Friction causes them to slow down immediately.

Flashcards
Newton's First Law
Newton's First Law
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Force and Change in Motion
Force and Change in Motion
A larger force produces a greater change in motion for an object with the same mass. A larger mass requires a greater force to produce the same change in motion.
Frictionless Surface
Frictionless Surface
A surface where there is no force opposing motion, allowing objects to move without slowing down.

Study Notes
Force and Acceleration
-
Equal Forces: Two objects pushing each other exert equal and opposite forces (Newton's Third Law). The strength of the push is the same for both, regardless of their mass.
-
Unequal Acceleration: The object with less mass experiences a greater acceleration (Newton's Second Law). Acceleration is inversely proportional to mass. For example, if two objects experience the same force, the object with a smaller mass will accelerate at a greater rate.
-
Example: A 150 kg shot-putter and a 75 kg golfer pushing each other exert equal forces. The golfer, having less mass, will experience twice the acceleration of the shot-putter.
-
Motion after Contact: Without external forces (like friction), objects will maintain constant velocity in a straight line (Newton's First Law).
