Speed, Acceleration, and Gravity

Front

What is acceleration due to gravity?

Back

The acceleration experienced by an object due to gravity, typically denoted as 9.81 m/s² on the surface of the Earth.

Front

What is an example of negative acceleration (or deceleration)?

Back

A car approaching a red light.

Front

What is the net force acting on an object?

Back

The total force acting on an object, taking into account all the individual forces and their directions.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the change in velocity divided by the time interval over which the change occurs.

Front

What is the formula for acceleration?

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.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the effect of gravity on falling objects?

Back

All objects fall at the same rate in a vacuum, regardless of their mass, due to the acceleration of gravity.
