Forces and Motion--5th Grade

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed can be calculated using the formula: Speed = Distance / Time.

Front

What is a force?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is the relationship between mass and force?

Back

According to Newton's second law, Force = Mass x Acceleration (F = ma). More mass requires more force to accelerate.

Front

What is balanced force?

Back

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

Front

What is unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.
