Physics Semester 1 review AB

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t)

Front

What does a constant velocity indicate about an object's motion?

Back

Constant velocity means that an object is moving at the same speed and in the same direction over time.

Front

What forces act on a car moving at constant velocity?

Back

Gravity, Normal force, Friction, and Applied force.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What happens to the net force when an object is in equilibrium?

Back

When an object is in equilibrium, the net force acting on it is zero.

Front

What is the direction of the net force on a rollercoaster at the top of a loop?

Back

The net force is directed towards the center of the circle.

Front

What is the difference between speed and velocity?

Back

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

Front

What does a horizontal line on a distance-time graph represent?

Back

A horizontal line on a distance-time graph represents no motion.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
