Force and Motion

Front

What is the definition of force in physics?

Back

A force is a push or pull that can change the motion of an object.

Front

What are the two types of forces?

Back

Contact forces and non-contact forces.

Front

Give an example of a contact force.

Back

Friction, tension, and normal force are examples of contact forces.

Front

What is an example of a non-contact force?

Back

Magnetism and gravity are examples of non-contact forces.

Front

What tool is commonly used to measure time in experiments?

Back

A stopwatch.

Front

What is the effect of a push on an object?

Back

A push can cause an object to accelerate, change direction, or stop.

Front

What is the effect of a pull on an object?

Back

A pull can cause an object to move closer or change its position.

Front

How does friction affect motion?

Back

Friction opposes motion, making it harder for objects to slide past each other.

Front

What is the relationship between force and motion?

Back

Force is required to change the motion of an object; without force, an object will remain at rest or in uniform motion.

Front

What is inertia?

Back

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