What is the formula for speed?

• Distance × Time

• Distance ÷ Time

• Time ÷ Distance

• Time × Acceleration

A car travels 60 miles in 2 hours. What is its speed?

• 30 mph

• 60 mph

• 120 mph

• 15 mph

If an object moves with constant speed, its acceleration is:

• Positive

• Negative

• Zero

• Increasing

Acceleration is defined as the change in:

• Speed divided by distance

• Velocity divided by time

• Time divided by distance

• Force divided by mass

A train accelerates from rest to 40 m/s in 8 seconds. What is its acceleration?

• 5 m/s²

• 10 m/s²

• 4 m/s²

• 8 m/s²
