Question

if you apply the same amount of force to two different objects, the object with less mass will experience:
a) greater acceleration
b) less acceleration
c) the same acceleration
d) no acceleration

which unit is used to measure acceleration?
a) kilograms (kg)
b) newtons (n)
c) meters (m)
d) meters per second squared (m/s²)

Explanation:

First Question (Force and Acceleration)

From Newton's second law \( F = ma \) (where \( F \) is force, \( m \) is mass, \( a \) is acceleration), rearranged as \( a=\frac{F}{m} \). If force \( F \) is constant, acceleration \( a \) is inversely proportional to mass \( m \). So a smaller mass means greater acceleration.

• Kilograms (kg) measure mass.
• Newtons (N) measure force.
• Meters (m) measure length or distance.
• Acceleration is the rate of change of velocity, so its unit is meters per second squared (\( \text{m/s}^2 \)) (assuming the last option is "Meters per second squared").

Answer:

A. Greater acceleration
