Front

What is the acceleration of a car that goes from 20 m/s to 100 m/s in 2 seconds?

Back

40 m/s²

Front

A car accelerates from a standstill to 70 m/s in 10 seconds. What is the acceleration?

Back

7 m/s²

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

Define force in terms of mass and acceleration.

Back

Force = Mass × Acceleration (F = ma)

Front

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

Back

Newton (N)

Front

What does a negative acceleration indicate?

Back

The object is slowing down.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight line from the initial to the final position.
