free fall conceptual physics

Front

What happens to the total distance that a ball travels as it falls off the side of a cliff?

Back

The distance increases at a nonuniform rate.

Front

What is the average speed of a toy car that moves 8 meters in 4 seconds?

Back

2 m/s.

Front

When an object falls, what is the nature of its acceleration?

Back

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

Front

What is the gravitational acceleration of an object in a vacuum near the surface of the Earth?

Back

g = 9.8 m/s².

Front

What is the distance a ball falls after 1, 2, 3, 4, and 5 seconds using g = 10 m/s²?

Back

5, 20, 45, 80, 125 m.

Front

Define free fall in physics.

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force.

Front

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

Back

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

Front

What does the symbol 'g' represent in physics?

Back

'g' represents the acceleration due to gravity, approximately 9.8 m/s² on Earth.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
