Forces and Motion Concepts

Front

What is force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is gravity?

Back

Gravity is the force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can be an increase or decrease in speed.

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are not equal, causing an object to accelerate in the direction of the greater force.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

What is inertia?

Back

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

Front

What is a Newton?

Back

A Newton (N) is the unit of measurement for force in the International System of Units (SI).

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
