7th Ch. 2 Motion, Forces, and Newton's Laws Pre/Post Flashcardizz

Front

What does displacement measure?

Back

Displacement measures the distance and direction between the starting and stopping points.

Front

What does Newton's third law of motion state?

Back

Newton's third law of motion states that when a force is applied on an object, there is an equal force applied by the object in the opposite direction.

Front

What is the formula for speed?

Back

Speed is calculated as distance divided by time.

Front

What happens to the net force when balanced forces act on an object?

Back

When balanced forces act on an object, the net force is zero.

Front

What factors affect the strength of gravitational force between two objects?

Back

The strength of the gravitational force depends on the mass of the objects and the distance between them.

Front

Define force.

Back

A force is a push or pull on an object that can cause it to accelerate.

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 is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated by dividing the change in velocity by the time taken.
