Acceleration

Front

What is the SI unit for acceleration?

Back

m/s²

Front

What does it mean if an object has no acceleration?

Back

An object has no acceleration if it is moving at a constant speed in a straight line or is at rest.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What factors affect a car's acceleration?

Back

A car's acceleration depends on its mass and the force applied to it.

Front

If a box slides down an inclined plane and reaches a velocity of 27 m/s in 3 seconds, what is its acceleration?

Back

9 m/s²

Front

What is the acceleration of a car that starts from rest and reaches 20 m/s in 3.5 seconds?

Back

5.7 m/s²

Front

What is the difference between speed and acceleration?

Back

Speed is how fast an object is moving, while acceleration is the rate of change of speed.

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the formula for calculating acceleration in a straight line?

Back

a = (v_f - v_i) / t, where a is acceleration, v_f is final velocity, v_i is initial velocity, and t is time.
