Physics Semester 1 Review

Front

Which graph represents a car approaching a red light?

Back

Graph B shows a decreasing velocity, indicating the car is slowing down as it approaches the red light.

Front

What does a flat line on a velocity-time graph indicate?

Back

A flat line indicates constant velocity, meaning the object is moving at a steady speed without acceleration.

Front

What is the equation for calculating velocity?

Back

The equation for velocity is v = d/t, where 'v' is velocity, 'd' is distance, and 't' is time.

Front

What is the definition of velocity?

Back

Velocity is the rate and direction of an object’s motion, defined as the change in position over time.

Front

Which of Newton's Laws explains why you fly off a skateboard when hitting a curb?

Back

This situation is best explained by Newton's First Law, which states that an object in motion stays in motion unless acted upon by an external force.

Front

What is acceleration?

Back

Acceleration is the rate at which an object’s velocity changes over time.

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 positive slope on a distance-time graph represent?

Back

A positive slope indicates that the object is moving away from the starting point.

Front

What is the formula for calculating acceleration?

Back

The formula for acceleration is a = (v_f - v_i) / t, where 'v_f' is final velocity, 'v_i' is initial velocity, and 't' is time.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.
