Question

match the correct term in column i with its definition in column ii.
i
______ kinetic
______ centripetal
______ mass
______ acceleration
______ velocity
______ weight
______ gravity
______ inertia
______ speed
______ momentum
______ newton
ii
a) amount of matter in an object
b) amount of force exerted on an object due to gravity
c) distance covered per unit of time
d) rate at which velocity changes over time
e) speed in a given direction
f) unit of measurement for force
g) energy of motion
h) tendency of a moving object to keep moving
i) depends on the mass and velocity of an object
j) type of force that keeps objects moving in a circle
k) attractive force between two objects

Explanation:

• Kinetic: Kinetic energy is the energy of motion, so it matches with "energy of motion" (g).
• Centripetal: Centripetal force is the type of force that keeps objects moving in a circle, so it matches with "type of force that keeps objects moving in a circle" (j).
• Mass: Mass is the amount of matter in an object, so it matches with "amount of matter in an object" (a).
• Acceleration: Acceleration is the rate at which velocity changes over time, so it matches with "rate at which velocity changes over time" (d).
• Velocity: Velocity is speed in a given direction, so it matches with "speed in a given direction" (e).
• Weight: Weight is the amount of force exerted on an object due to gravity, so it matches with "amount of force exerted on an object due to gravity" (b).
• Gravity: Gravity is the attractive force between two objects, so it matches with "attractive force between two objects" (k).
• Inertia: Inertia is the tendency of a moving object to keep moving, so it matches with "tendency of a moving object to keep moving" (h).
• Speed: Speed is the distance covered per unit of time, so it matches with "distance covered per unit of time" (c).
• Momentum: Momentum depends on the mass and velocity of an object, so it matches with "depends on the mass and velocity of an object" (i).
• Newton: Newton is the unit of measurement for force, so it matches with "unit of measurement for force" (f).

Answer:

• Kinetic - g
• Centripetal - j
• Mass - a
• Acceleration - d
• Velocity - e
• Weight - b
• Gravity - k
• Inertia - h
• Speed - c
• Momentum - i
• Newton - f
