Physics Final Review

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object. It determines the object's acceleration and direction of motion.

Front

How do you calculate net force when multiple forces are acting in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is the formula for acceleration?

Back

Acceleration (a) is calculated using the formula a = (final velocity - initial velocity) / time.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is distance in physics?

Back

Distance is a scalar quantity that represents the total path length traveled by an object, regardless of direction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a distance-time graph represent?

Back

A distance-time graph shows how distance changes over time, indicating the speed and direction of an object's motion.

Front

What is the significance of the slope in a distance-time graph?

Back

The slope of a distance-time graph represents the speed of the object; a steeper slope indicates a higher speed.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no other forces acting on it.

Front

What is the formula for calculating distance in free fall?

Back

Distance (d) can be calculated using the formula d = 0.5 * g * t², where g is the acceleration due to gravity and t is time.
