Forces and Motion

Front

What causes objects to move?

Back

Unbalanced forces

Front

What is the 2nd Law of Motion?

Back

The Law of Acceleration states that it is harder to push a full grocery cart than an empty grocery cart.

Front

What is friction?

Back

A force that opposes motion between any surfaces that are touching.

Front

What is acceleration?

Back

Any change in an object's speed or direction.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What is the effect of gravity on objects in motion?

Back

Gravity pulls objects toward the center of the Earth, affecting their motion.

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.
