Physics Chapter 3 Study Slides

Front

What is the standard acceleration due to gravity near the Earth's surface?

Back

9.8 m/s².

Front

What happens to the acceleration of an ice crystal as it falls through the air?

Back

It decreases because of air resistance.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the acceleration of a fighter jet that goes from +100 m/s to +230 m/s in 10 seconds?

Back

+13 m/s².

Front

In which scenario does a car have no acceleration?

Back

A car with the cruise control set at 80 km/h going down a straight highway.

Front

What does it mean for an object to be in free fall?

Back

An object is in free fall when the only force acting on it is gravity.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air.

Front

What is the difference between speed and velocity?

Back

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

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's velocity changes at a constant rate.

Front

What is the formula for calculating distance traveled under constant acceleration?

Back

Distance = Initial Velocity × Time + 0.5 × Acceleration × Time².
