Physics Unit 1 Review

Front

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

Back

Distance = Speed × Time

Front

Define speed in physics.

Back

Speed is a scalar quantity that refers to how fast an object is moving, measured as distance traveled per unit of time.

Front

Define velocity in physics.

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including direction.

Front

What is the difference between speed and velocity?

Back

Speed is scalar (magnitude only), while velocity is vector (magnitude and direction).

Front

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

Back

600 meters

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 covered by a train moving at a speed of 80 km/h for 2 hours.

Back

160 km

Front

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

Back

The object is slowing down.

Front

What is the unit of speed in the International System of Units (SI)?

Back

Meters per second (m/s).

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed × Time.
