Physics Unit 1 Review

Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

A car travels at a constant speed of 50 km/h for 3 hours. What is the total distance traveled?

Back

150 km

Front

Calculate the distance traveled by a car moving at a speed of 60 m/s for 10 seconds.

Back

600 meters

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time.

Front

A car accelerates from rest at a rate of 2 m/s². What is its velocity after 5 seconds?

Back

10 m/s

Front

Explain the difference between speed and velocity.

Back

Speed is scalar, velocity is vector.

Front

What does negative acceleration indicate about an object's motion?

Back

The object is slowing down.

Front

Define speed.

Back

Speed is the distance traveled per unit of time, a scalar quantity.

Front

Define velocity.

Back

Velocity is the speed of an object in a given direction, a vector quantity.

Front

What is the unit of acceleration in the SI system?

Back

Meters per second squared (m/s²).
