Newest Kinematic equations and free fall

Front

What is the initial velocity of an object that starts from rest?

Back

0 m/s

Front

What happens to an object in free fall in a vacuum?

Back

It accelerates at a constant rate until it hits the ground.

Front

If a feather and a metal bolt are dropped from the same height in a vacuum, which hits the ground first?

Back

They would hit the ground at the same time.

Front

What unit is used to measure time in physics?

Back

s (seconds)

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.8 m/s².

Front

What is free fall?

Back

The motion of an object under the influence of gravitational force only.

Front

What is terminal velocity?

Back

The constant speed an object reaches when the force of gravity is balanced by air resistance.

Front

What is the formula for calculating the distance fallen during free fall?

Back

d = 0.5 * g * t², where g is the acceleration due to gravity and t is time.

Front

What does the slope of a velocity-time graph represent?

Back

The acceleration of the object.

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).
